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. [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. 2. 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). Annually, around 70 to 90 cyclonic systems develop all over the globe. This was based on forecasts of a category 5 cyclone. 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. Approximately an hour after landfall, Marcia had weakened to a Category 4. The Coriolis force causes the wind to spiral around a low-pressure area. Marcia was tracked over the next few days as it drifted eastward with little change in intensity (Figure 1). 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. The low tracked further southeast during 21 February and crossed the Sunshine Coast back out to sea at 3 pm 21 February. 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. [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. 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). A category two cyclone's strongest winds are DESTRUCTIVE winds with typical gusts over open flat land of 125-164kph. 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 severe tropical storm is designated as a tropical cyclone when it reaches wind speeds of 64 knots (118 km/h, 74 mph). This increase in intensity is well above the average rate of intensification for tropical cyclones anywhere in the world. [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. [33] Total damage in Queensland reached A$750 million (US$587 million). Marcia was downgraded to a tropical low at 2 am Saturday 21 February, located to the south of Monto. 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. Cyclone Marcia, meanwhile, has recorded wind speeds of as much as 285km/h, with sustained winds of 205km/h, Mr Perkins said. 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. [13][14] Maintaining strength, Marcia made landfall over the coast near Shoalwater Bay at 22:00 UTC (08:00 AEST on 20 February). 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. [21] Although it drifted northwards over warmer SST later, it was failed to intensify but weakened further.

The storm tide gauge at Port Alma almost recorded water levels close to but not exceeding HAT as the surge coincided with low tide. 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. I see the wind speed at the airport is only 6 kts. Late on February 19th, Marcia made a sharp turn towards the south and intensified even further, and was estimated to have reached category 5 intensity at 4am on Friday 20th February (Figure 2.). 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. 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. Eventually, the cyclone weakened, moved southeast out to sea, before dissipating. The cyclone then tracked in a sout-south-easterly direction, impacting many communities … [20], The ex-tropical cyclone arrived in the Coral Sea from the southeast coast of Queensland on 21 February. Satellite images and tracking maps of Category 5 Tropical Cyclone Marcia 2015, February 17 - 22. The analysis procedure, findings and limitations will be discussed.

Cyclone Marcia is a category 5 tropical cyclone, the highest classification given to a storm. Months later, houses are still permanently damaged. [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. 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. 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. Almost 3000 people requested assistance from the SES – including 800 in central Queensland. RN: On February 25, RN Afternoons reported winds speeds of up to 285km/h in Rockhampton during Cyclone Marcia. Cyclone Nivar Cyclone Nivar to cross Tamil Nadu and Puducherry coasts with wind speed of 120-130 km per hour on Wednesday: IMD. After landfall, the Queensland Disaster Recovery Committee convened. J. 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 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. Cyclone wind speeds differ greatly depending on distance from the eye of the storm. Provide location-specific wind-speed information. Climate change is expected to make tropical cyclones less frequent but more severe on average.
