Harvey Moving Over Gulf of Mexico Rains Winds Increasing Again
Harvey Moving Over Gulf of Mexico Rains Winds Expanding Again
Tropical Storm Harvey continues to move southeastward with the center now just offshore. There has been an increase in convection to the north and northwest of the center this afternoon as the radar below shows. The satellite loop shows the southeast motion clearly and Tropical Storm Harvey may get out into the Gulf of Mexico by about 50-75 miles or so. Water temperatures in that part of the Gulf of Mexico have dropped almost 10 degrees to the upper 70s and lower 80s which will work against regeneration but some strengthening is possible since a solid outflow is evident. Watch the radars this evening and overnight for this possibility.The expanding area of heavy rain is moving into the Houston Galveston corridor again. This is not good at all for an area that has already seen 2 to 3 feet of rain.
