The Bureau was criticised for continuing to report the ADT estimates even after lower actual windspeeds had been recorded, notably by Jennifer Marohasy of Central Queensland University. Based on all the evidence collected and detailed reanalysis of satellite imagery, severe tropical cyclone Marcia crossed the coast at Shoalwater Bay (north northwest of Yeppoon) as a category 5 system at around 8am AEST on February 20th. Severe tropical cyclone Marcia was a relatively compact system compared to other severe tropical cyclones such as severe tropical cyclone Yasi and weakened quickly as it moved over land during the day. Severe Tropical Cyclone Marcia was a powerful tropical cyclone that made landfall at its peak strength over central Queensland, near Shoalwater Bay on 20 February 2015. 2. [30], The Global Disaster Alert and Coordination System issued an advisory at 06:00 UTC on 20 February stating that up to 92,000 people had been affected by Category 1 winds or higher. There was however evidence of significant erosion and large deposits of pumice stone indicative of much higher water levels being reached on beaches to the north of Yeppoon between One Mile Beach and Farnborough Beach, and particularly at 9 Mile Beach. [33] Total damage in Queensland reached A$750 million (US$587 million). Significant structural damage occurred in the Yeppoon area and along the Capricorn Coast, with a number of houses having roofs blown off and walls torn down. [15], On 20 February, despite good poleward outflow, Marcia began to track southeastwards along the western periphery of the subtropical ridge and rapidly weakened due to land interaction and increasing vertical wind shear, yet the JTWC issued the final warning during sunset. [32] Heavy rain fell across several regions and authorities evacuated residents from the small town of Jambin, south-west of Rockhampton, as localised flooding took place, which also affected Biloela. North Queensland Strata Title Inspection Program (NQSTIP) to assess the resilience and reduce cyclone impacts of Strata Title Properties. ANIMATED MULTISPECTRAL SATELLITE IMAGERY ALONG WITH ENHANCED INFRARED SATELLITE IMAGERY SHOWS THAT TC 13P MADE LANDFALL AT APPROXIMATELY 19/2200Z AND HAS STARTED TO RAPIDLY DETERIORATE … The Global Disaster Alert and Coordination System issued an advisory at 06:00 UTC on 20 February stating that up to 92,000 people had been affected by Category 1 winds or higher. During the afternoon of Wednesday February 18th, the low pressure system reached tropical cyclone intensity and was named Marcia, before beginning to move towards the southwest. The tropical low that eventually became severe tropical cyclone Marcia was first identified in the Coral Sea on Sunday, February 15th 2015. Analysis of radar imagery indicated that the strongest part of the eye wall missed the automatic weather station and it is concluded that parts of Rockhampton experienced winds of high-end category 2 strength. February 18 00:32UTC - February 10 14:32UTC, February 19 01:00UTC - Febraury 20 03:00UTC, February 16 00:00UTC - February 22 18:00UTC, This page was created at 18:53 on Thursday 24 December 2020 (UTC), © Copyright Commonwealth of Australia 2020, Bureau of Meteorology (ABN 92 637 533 532) | CRICOS Provider 02015K | Disclaimer | Privacy | Accessibility, Shoalwater Bay, 90km north northwest of Yeppoon, 'Severe tropical cyclone Marcia: storm tide and wave monitoring data', Don and Dee Rivers and Callide Creek in the Fitzroy River catchment, Burnett River and Three Moon Creek in the Burnett River catchment, Mary River, Six Mile Creek and Tinana Creek in the Mary River catchment. Tropical cyclone Marcia continued to intensify during February 18th and was estimated to have reached category 2 intensity by that evening. [1] The cyclone went on to affect various areas including Yeppoon and Rockhampton. A large storm surge was recorded across the Capricorn coastline, with significant beach erosion and structural damage impacting Great Keppel Island in particular (Figure 9). [24][25], Prior to the category 5 storm making landfall the Premier of Queensland, Annastacia Palaszczuk, stated that South East Queensland should not expect a repeat of January 2011. Cyclone wind speeds differ greatly depending on distance from the eye of the storm. [34], The observed windspeeds were lower than the analyzed maximum sustained winds, which had been estimated using the Advanced Dvorak Technique. It is believed that only a small part of the coastline within about 15km of the cyclone centre would have experienced category 5 strength winds. RN: On February 25, RN Afternoons reported winds speeds of up to 285km/h in Rockhampton during Cyclone Marcia. A demonstration of the force of a cyclone’s winds. Climate change is expected to make tropical cyclones less frequent but more severe on average. The eye of Marcia passed directly over Townshend Island (Figure 2) within the SWBTA and experienced the full force of winds when at category 5 intensity. When the cyclone makes landfall, wind speed will be at 110-120kmph gusting to 145kmph in Nagapattinam, Karaikal, Mayiladuthurai, Cuddalore, Puducherry, Villupuram and … 738 FOPZ13 KNHC 070245 PWSEP3 POST-TROPICAL CYCLONE MARIE WIND SPEED PROBABILITIES NUMBER 32 NWS NATIONAL HURRICANE CENTER MIAMI FL EP182020 0300 UTC WED OCT 07 2020 AT 0300Z THE CENTER OF POST-TROPICAL CYCLONE MARIE WAS LOCATED NEAR LATITUDE 22.5 NORTH...LONGITUDE … Cyclone Nivar Cyclone Nivar to cross Tamil Nadu and Puducherry coasts with wind speed of 120-130 km per hour on Wednesday: IMD. The central pressure of a cyclone needs to be somewhere in the 970 to 955 hPa range to be a Category 3. It was later replaced with Mingzhu in October 2016. The DSITI storm tide gauge at Port Alma observed a storm surge of 2.0 metres (Figure 11) while the wave rider buoy at Emu Park registered a significant wave height of 4.1m and peak height of 7.0 metres with waves coming from the northeast and a peak period of 9 to 10 seconds (Figure 12). [17][18][19] The BoM's final technical bulletin of Marcia indicated that the cyclone had eventually weakened into a tropical low at 15:00 UTC (01:00 AEST on 21 February), with the asymmetric wind structure and unimpressive observations. [16] The system weakened into a category 3 cyclone at 13:00 AEST (03:00 UTC), lost the severe tropical cyclone intensity at 17:00 AEST (07:00 UTC) and even weakened into a category 1 cyclone at 20:00 AEST (10:00 UTC). The maximum sustained wind speed, however, never exceeded 156 km/h, and the central pressure was never less than 972 hPa. Almost 3000 people requested assistance from the SES – including 800 in central Queensland. Should a tropical cyclone intensify further and reach wind speeds of 90 knots (166 km/h, 103 mph), it will be classified as an intense tropical cyclone. This was based on forecasts of a category 5 cyclone. The storm is wreaking havoc in parts of Tamil Nadu and Puducherry, authorities have been forced to extend the public holiday till today and shut operations at the Chennai airport till 9 AM. [6] At 09Z, the BoM reported that the tropical low intensified into a category 1 tropical cyclone and named it Marcia, as it had started to track southwestwards along the northwestern periphery of a low- to mid-layered subtropical ridge. High resolution radar imagery (Figure 3) shows that Middle Percy Island was located just outside the eye wall of Marcia (represented by the strong reflectivity returns near the centre of the system). There was structural damage to houses, uprooted trees, downed power lines and evidence of storm surge elsewhere in parts of the Capricornia district, including (but not limited to) the towns of Byfield (Figure 6), Yeppoon (Figure 7 and 8) and Rockhampton. community that receives an over-represented wind speed report may have potential for From: AMOS 2015: Australian Meteorological and Oceanographic Society National Conference 2015, 15-17 July 2015, Brisbane, QLD, Australia. The JTWC monitored Marcia again on 22 February and claimed that the system had become subtropical with gale-force sustained winds, when sea surface temperature (SST) was approximately 25 °C; moreover, satellite imageries also revealed a broad, exposed low-level circulation centre (LLCC) with deep convection displaced over the southeast periphery of the LLCC. [10][11][12] Soon afterwards, it turned southwards along the western periphery of a subtropical ridge and reached peak intensity at 18:00 UTC as a category 5 severe tropical cyclone with 10-minute maximum sustained winds at 205 km/h (125 mph), featuring a very well-defined 35 km (20 miles) eye. The cyclone then moved in a southerly direction overland, near to the coast. Annually, around 70 to 90 cyclonic systems develop all over the globe. The analysis procedure, findings and limitations will be discussed. Prior to landfall in the early hours of February 20th, the automatic weather station on Middle Percy Island recorded a maximum sustained (10 minute average) wind speed of 84 knots (156 km/h) and a maximum wind gust of 112 knots (208 km/h), or the equivalent of a strong category 3 system. The eye of Marcia passed over the city of Rockhampton where a maximum wind speed (10 minute average) of 40 knots (75 km/h) was recorded at the automatic weather station at Rockhampton Airport. [22][23] The remnants were completely absorbed into a trough on 1 March. The Coriolis force causes the wind to spiral around a low-pressure area. When the winds speed is 39 mph (63 kmph), the storm is called a "tropical storm". Cyclone Marcia is a category 5 tropical cyclone, the highest classification given to a storm. The storm tide gauge at Port Alma almost recorded water levels close to but not exceeding HAT as the surge coincided with low tide. "[26] BOM rejected the criticism, stating that Percy Island was not located in the region of highest windspeed. Months later, houses are still permanently damaged. [27] More than 800 people bunkered down in the Yeppoon Cyclone Shelter, the most southerly located cyclone shelter in Queensland, located within the grounds of the Yeppoon State High School. Whereas when the wind speed reaches 74 mph (119 kmph), the storm is officially a "tropical cyclone" or hurricane. Mason, M., Smith, D., and Henderson, D. (2015) Inference of surface wind speeds during Tropical Cyclone Marcia based on damage observations. Fortunately, the storm surge from Marcia along the coast near and to the south of Yeppoon coincided with a falling tide and did not produce significant inundation or damage. [4] Late on the same day, the BoM began to issue technical bulletins and designated the tropical low as 14U, although the bureau initially forecasted that it would only intensify into a category 1 cyclone prior to landfall. This increase in intensity is well above the average rate of intensification for tropical cyclones anywhere in the world. Cyclone Marcia, meanwhile, has recorded wind speeds of as much as 285km/h, with sustained winds of 205km/h, Mr Perkins said. Bureau Home > Tropical Cyclones > Past Tropical Cyclones > Severe Tropical Cyclone Marcia. The cyclone is still officially classified by the bureau as a Category 5.[36]. DH Picks. The area of Shoalwater Bay, where Marcia made landfall, had widespread areas of uprooted trees and evidence of storm surges and beach erosion, particularly along the coast north of Yeppoon. In: [Presented at Australian Meteorological and Oceanographic Society National Conference 2015]. [5] The JTWC upgraded the partially exposed system to a tropical cyclone and designated it as 13P early on 18 February, which also forecasted that it would intensify slightly. Nearby towns and hamlets took their own precautions to protect themselves. The Shoalwater Bay Training Area (SWBTA) is used for military training exercises by the Australian Defence Force and as a result is largely uninhabited with limited buildings. 600 wind speed measurements per min . The very serious cyclonic storm Nivar has resulted in major havoc in many South Indian states and cities, the cyclone resulted in a landfall between Puducherry and Marakkanam. Provide location-specific wind-speed information. Thursday February 19th, saw tropical cyclone Marcia continue on a south-westerly track and undergo a period of extremely rapid intensification, increasing by two categories to a category 4 severe tropical cyclone in approximately 12 hours. [28][29] The heaviest rainfall was recorded over the Don and Dee Rivers and Callide Creek in the Fitzroy River area where up to 300 millimetres of rainfall was recorded in a 6–8-hour period during the afternoon and evening of 20 February. This weather station was located to the west of tropical cyclone Marcia's core and would not have experienced the cyclone's maximum winds in its eye-wall. Marcia was the first cyclone of the 1974/75 tropical cyclone season to operate in the Northwestern Australian Region. A wind gust of 208 km/hr was recorded at 4.30 am, which suggests Marcia was almost a Category 3 at this time, even though its central pressure was never recorded as below 970 hPa. A category two cyclone's strongest winds are DESTRUCTIVE winds with typical gusts over open flat land of 125-164kph. Post-Tropical Cyclone Marie Wind Speed Probabilities. The bureau categorises tropical cyclone intensity according to the maximum mean wind speed over open, flat land or water. Severe Tropical Cyclone Marcia crossed the coast at Shoalwater Bay (north northwest of Yeppoon) during the morning of 20th February 2015. Last week's swell, at least looking at the charts that I was, had tremendous fetch while most of the really powerful winds were running down the coast rather than into the coast. Marcia was tracked over the next few days as it drifted eastward with little change in intensity (Figure 1). J. [6][7], When Marcia intensified into a category 2 tropical cyclone at 00:00 UTC on 19 February, it had developed a central dense overcast with a consolidating eyewall because of weakening vertical wind shear. Drawing energy from the sea surface and maintaining its strength as long as it remains over warm water, a tropical cyclone generates winds that exceed 119 km (74 miles) per hour. The cyclones are the first to make landfall on mainland Australia this season, the third latest arrival in the past 50 years, the bureau said this week. Due to its impact, the Australian Bureau of Meteorology retired the name Marcia. Marcia was downgraded to a tropical low at 2 am Saturday 21 February, located to the south of Monto. Yeppoon, nearer to the landfall of TC Marcia, was also undertaken to estimate the probable maximum wind speed and storm structure. Approximately an hour after landfall, Marcia had weakened to a Category 4. Local Councils offered sandbags to residents who were likely to be affected by flooding. complacency in preparation or building standards in the future. As the cyclone passed to the east, Middle Percy Island experienced wind gusts of 208 kilometres per hour, with a maximum recorded speed of 295 kilometres per hour. Max wind speed 230km/h. Marcia crossed the coast at category 5 intensity in a largely uninhabited area, although significant damage was recorded at Yeppoon and Rockhampton as the system weakened after making landfall. Cyclones have wind speed but can produce very little. This makes Marcia a category 3 based on the Australian system, and only a category 2 based on the Saffir-Simpson Hurricane Wind Scale. tropical cyclone (tc) 13p (marcia), located approximately 262 nm north-northwest of brisbane, australia, has tracked southward at 10 knots over the past six hours. Aerial photography taken very soon after the passage of Marcia shows almost complete defoliation of trees on Townshend Island (Figure 4). It passed just to the west of Yeppoon as a Category 4 system, then traversed over the regional city of Rockhampton as a Category 2 system on the same day. The cyclone then tracked in a sout-south-easterly direction, impacting many communities … The Saffir-Simpson hurricane wind scale. Cyclone Nivar is the second cyclone in the Bay of Bengal this year. The eye of Marcia passed over the city of Rockhampton where a maximum wind speed (10 minute average) of 40 knots (75 km/h) was recorded at the automatic weather station at Rockhampton Airport. (2015) Comparison of near-surface wind speed estimation in the 22 May, 2011 Joplin, Missouri Tornado. Lombardo, F.T., Roueche, D.B., Prevatt, D.O. Structural damage also occurred across Rockhampton and in the townships of Marmor and Mount Larcom. A severe tropical storm is designated as a tropical cyclone when it reaches wind speeds of 64 knots (118 km/h, 74 mph). Category three (severe tropical cyclone) Some roof and structural damage. Marcia caused at least A$750 million (US$587 million) worth of damage. [13][14] Maintaining strength, Marcia made landfall over the coast near Shoalwater Bay at 22:00 UTC (08:00 AEST on 20 February). Heavy rainfall associated with tropical cyclone Marcia affected catchments extending from the far eastern parts of Fitzroy River catchment south to the Queensland - New South Wales border. The Australian Bureau of Meteorology (BoM) started to monitor a tropical low which developed within the monsoon trough to the southeast of Papua New Guinea on 15 February. After landfall, the Queensland Disaster Recovery Committee convened. Australia is suffering a rare “cyclone sandwich” – two gigantic tropical cyclones, Cyclone Marcia (cat 5 – like Katrina) and Cyclone Lam (cat 4) are smashing into the North of Australia at the same time as seen in the NASA/NOAA satellite photo. The coastline of Pearl Bay (Figure 2 and Figure 5) clearly shows extensive tree defoliation and soil erosion as it experienced the outer edge of the very destructive wind core generated by Marcia at its maximum intensity just before landfall. Flooding above the major flood level occurred in the following basins: For more information on the flooding that was produced by severe tropical cyclone Marcia see here. Brisbane weather, Tropical Cyclone Marcia to bring 260kmh winds By Jorge Branco Updated February 20, 2015 — 12.01am first published February 19, 2015 — 6.22pm Eventually, the cyclone weakened, moved southeast out to sea, before dissipating. It was a small system of only moderate intensity and maximum winds associated with it are estimated to have reached about 90 km/h on 20th October. I see the wind speed at the airport is only 6 kts.

[35] The International Wind Hazard Damage Assessment Group also expressed concern, saying "A Bureau chief Robb Webb also rejected claims BOM had relied solely on modelling, noting that the bureau worked with the US Joint Typhoon Warning Center to predict the storm's strength. These winds correspond to Beaufort 10 and 11 (storm and violent storm). On 27 February, Marcia entered the responsible area of the Fiji Meteorological Service as a weak low-pressure system. Access to the area is restricted but permission was granted to a team of Bureau of Meteorology and Queensland Department of Science, Information Technology and Innovation (DSITI) staff on the 8-9 March 2015. The low tracked further southeast during 21 February and crossed the Sunshine Coast back out to sea at 3 pm 21 February. At that time, intensity estimates inferred from satellite imagery indicated Marcia was a category 5 system at its core.
