Gustav Gets Closer to Land

As of this evening, around 10:54 pm EST, Hurricane Gustav is continuely moving towards the Louisiana coast at 16 mph in a NW direction with a wind speed of 115 mph and is located around 27.3 N, 88.1 W. It has increased slightly in pressure to 954 mb and the storm is starting to slow down as is it getting closer to land, but is still expected to make landfall sometime in the morning hours on Monday, September 1. ...

As of this evening, around 10:54 pm EST, Hurricane Gustav is continuely moving towards the Louisiana coast at 16 mph in a NW direction with a wind speed of 115 mph and is located around 27.3 N, 88.1 W. It has increased slightly in pressure to 954 mb and the storm is starting to slow down as is it getting closer to land, but is still expected to make landfall sometime in the morning hours on Monday, September 1. The storm is currently located 226 due south of New Orleans and moving Northwest so it is on the same track as previously expected. Hurricane Gustav will have two factors that will deter it from intensification: one is that it will interact with an increased wind sheer, and two is as it gets closer to the northern region of the gulf the water is shallower and the current is less effective to contribute to intensification. The storm has taken a circular shape as can be seen by the images produced from MODIS data below with hurricane force winds extending out 75 miles from the center and strong tropical winds beyond that. Tropical Storm Hanna 23.7N, 72.2W and has maximum sustained winds of 50 mph and a central pressure of 997 mb. Hanna has decreased in directional speed to 8mph. Due to the pressure ridge in Hanna\'s path it will prevent it from intensifying too much over the next several days. The storm is moving in a Northwest direction expected to make landfall on the Northern Florida/Georgia coast. There is an additional area of low pressure located off the Cape Verdes islands moving Westward at about 15 mph. This system has a high potential to develop into a depression in the next day or two.
