Hurricane Ivan made landfall early this morning near Gulf Shores, Alabama, as a strong Category 3 hurricane with maximum sustained winds of 130 mph. Ivan was an extremely large system, with hurricane force winds extending 100 miles from the storm center. Fortunately for New Orleans and Mobile, Ivan tracked slightly east of due north, sparing those cities from the most damaging winds and storm surge. As of 2 p.m. EDT, Thursday, September 16, 2004 Ivan was located about 45 miles west-northwest of Montgomery, Alabama, and continues its track to the north-northeast. The National Hurricane Center (NHC) expects Ivan to turn northeastward in the next 24 hours. Forward speed, currently 14 mph, is expected to diminish in that timeframe as well and there are indications than Ivan will stall. With maximum sustained winds down to 70 mph, Ivan is now a tropical storm. While losses could have been much higher had Hurricane Ivan made landfall further to the west than it did, AIR still expects significant damage and substantial losses, both due to the high wind speeds and to the sheer size of the storm system. While damage assessment is only just beginning, there have been reports of blown off roofs and significant numbers of downed trees. AIR also expects significant damage to mobile homes, siding and light structures. The AIR tropical cyclone team has run new scenarios using the most current information about Ivan’s meteorological parameters and its actual track. Five of these are now posted on the scenarios page of this website, where CATRADER® and CLASIC/2™ clients can view wind speed and loss maps. In addition, event sets representing the full range of simulated scenarios are now available for download.
