Ike Moves Over Cuba, Heads to the Gulf

As of 2:00 pm EST September 9th, Hurricane Ike has a forward speed to 12 mph heading in the West/Northwest direction with a wind speed of 75 mph and is located at approximately 22.7N, 83.4W with a central pressure of 970 mb.

As of 2:00 pm EST September 9th, Hurricane Ike has a forward speed to 12 mph heading in the West/Northwest direction with a wind speed of 75 mph and is located at approximately 22.7N, 83.4W with a central pressure of 970 mb. Hurricane Ike headed to Cuba as a category 3 storm initially and has weakened to a Category 1 storm as it moved over land. The storm is expected to continue in the West/Northwest direction due to a subtropical high pressure over the Northeastern part of the gulf that developed as a split from a larger high pressure system. Once the storm reaches the Gulf waters it is very likely that it will intensify due to its compact formation and the warm sea surface temperatures. The data shows colder SSTs left by Gustav in the Northern Gulf so if the storm would happen to move more North it will gain strength but not as much as if the storm continued west where the SSTs are slightly higher. For now the models show a possible low pressure system from the Western US moving to the north of Ike in 72 hours so the storm is expected to continue in a more west pattern. There is an uncertainty with the further forecasts so we\\\'ll have to monitor the storm once it moves into the Gulf. Hurricane Ike animations were created using the TRMM 3B42RT data of the Accumulated Rainfall parameter using the GES DISC TRMM Online Visualization and Analysis System (TOVAS)(http://disc2.nascom.nasa.gov/Giovanni/tovas/), which contains TRMM rainfall products, near-real-time 3-hourly, Multi-Satellite Precipitation Analysis, and rainfall ground observation data. An animation of Infrared was created using the Merged IR data which is a Globally-merged (60N-60S) pixel-resolution IR brightness temperature data (equivalent blackbody temps), merged from all available geostationary satellites (GOES-8/10, METEOSAT-7/5 & GMS). The data is available by ftp from the GES DISC (http://disc.sci.gsfc.nasa.gov/data/datapool/TRMM/01_Data_Products/06_Ancillary/01_Global_MERG_IR/index.html). The image shows the movement of the storms and formation pattern over a 20 hour period on 09-07-2008. Additional images are MODIS TERRA of Hurricane Ike on 09-08-2008, and an image generated by PODAAC at JPL (http://podaac.jpl.nasa.gov/hurricanes/) of the QuikSCAT Wind data.
