![]() Just prior to landfall, Idalia felt some wind shear and underwent an eyewall replacement cycle, knocking its intensity down a bit to a Category 3 hurricane at landfall along Florida's Big Bend coast. Moving over extremely warm Gulf of Mexico water, including the loop current, Idalia then rapidly intensified from Category 1 to 4 intensity in just 24 hours from Aug. Idalia almost made a complete counterclockwise loop while drifting around the northwestern Caribbean before finally pushing north into the Gulf of Mexico early on Aug. It then became Tropical Storm Idalia the following morning. Idalia's history: Tropical Depression Ten first formed just east of Cancún on Aug. Biggest increase in winds: 55 mph in 24 hours Highest rainfall total: 11.57" in Mullins, North Carolina Highest noted wind gust on land: 85 mph in Perry, Florida Biggest known storm surge: 8.9 feet in Cedar Key, Florida (likely much higher elsewhere, but unmeasured) Hurricane Idalia brought heavy rainfall, strong winds and feet of storm surge inundation to the Florida Gulf Coast in late August 2023 in the Gulf Coast's latest major hurricane onslaught.Īt its peak, Idalia was a Category 4 hurricane with 130 mph in the northeastern Gulf. Doppler observations can also reveal the presence of flocks of birds over Port Phillip Bay, which appear as thin lines, and generally have a higher velocity than the surrounding area.Sign up for the Morning Brief email newsletter and get the latest news and updates on Idalia’s path delivered straight to your inbox each weekday morning. These appear as radials of incorrect Doppler velocities in the area to the northeast of the radar. These echoes may be distinguished from rain as they do not move with the wind and end abruptly at the shoreline of the bay.Doppler observations are occasionally affected by multi path reflections off Melbourne City buildings and approaching rain bands. Because the radar has an unobstructed view of Port Phillip Bay out to about 25km, sea-clutter may be seen over the bay during strong winds. These usually become more noticeable on cold, clear, winter nights or early winter mornings. These echoes usually occur along ridges and peaks as isolated, stationary patches, being most common near the Yarra Ranges to the ENE and Mount Macedon to the north. Occasionally, some permanent echoes will not be completely removed from the display.

Non-meteorological aspects In most cases the processing of the radar signal removes permanent echoes caused by obstructions such as hills, buildings and other solid objects rather than rainfall. The location on the floor of a wide basin is ideal for Doppler observations which provide wind speed information. Similarly, cold fronts and associated rain and thunderstorms approaching from the northwest, through west and south are well detected. Summer thunderstorms that develop on the surrounding hills and mountains may be observed in detail. The high ground from the east, through north and to the south west tends to obscure shallow rain falling further away. Meteorological Aspects The radar is well sited to provide very good coverage for the Greater Melbourne Metropolitan Area. Animated weather radar views for the Tampa Bay area, powered by FOX 13s SkyTower - the first and most powerful television station radar in the nation. In 2002, Bay News 9 was the first TV station in the area to provide a VIPIR Doppler radar system. The most significant obstructions, starting from the east, are: Mt Dandenong 644m high, 53km to the east Yarra ranges 1219m, 83km to ENE Mt Macedon 1013m, 56km to the north Pentland Hills 763m and the Brisbane ranges 421m, 45km from the NNW through to the west and the You Yangs 363m, 30km to the SW.

Geographical Situation The radar is situated on the western plains of the Melbourne basin some 19km west-south-west of the Central Business District, about six kilometres from the western shores of Port Phillip bay and on a low rise about 20m above mean sea level. ![]()
