The 2008 Hurricane season has definitely begun. Tropical Storm Cristobal is moving further away from the East coast with wind speeds around 55 knots, with a pressure of 1002 mb. As the storm moves further North over cooler waters it will steadily weaken as it encounters high wind shear. It is located at approximately 39.1 N and 68.2 W, Northeast of the Delaware coast and is moving at approximately 21 mph. The storm will continue to move in a Northeast direction, later moving East and then Southeast following the Northern Subtropical Ridge. Unlike Cristobal, Tropical Storm Dolly is gaining strength as it heads towards Texas and Mexico. Dolly is moving in a Northwest direction and will be moving over slightly warmer waters allowing it to gain strength before it makes landfall. As of this morning it had maximum winds at 50 knots, with a central pressure of 997 mb and was centered at 23.3N, 93.8 W. There is an upper-level low pressure to the Northwest of the system that could contribute to Dolly strengthening, and Dolly has decreased in pressure as the storm continues to move at a rapid pace. The storm is expected to reach landfall as a category 1 storm but if it continues to strengthen and loses momentum it could strengthen to a strong category 1 with winds around 94 mph. Another system to keep an eye on is off the coast of Africa. The system hasn\'t organized yet but shows promise to develop into a tropical storm. The images of TS Cristobal, TS Dolly and the coastal system are generated using GrADs and the TRMM Globally-merged IR brightness temperature data, merged from all available geostationary satellites (GOES-8/10, METEOSAT-7/5 & GMS). The data is from July 20, 2008 at 23Z.
