Pressure down 12 mb from 1004 to 992 in three hours. If it drops another 18 mb in the next three hours then we are officially in an explosive deepening phase. Right now it's between rapid and explosive, but the pressure drop could accelerate as Alex gets more organized.

Agreed, he is deepening pretty good right now. It was always a case of the LLC getting underneath the convection. Probably will be a Hurricane, but don't think we will see any more real threat to the SE coastline. NC shore has a shot at getting a glancing blow. Hope I am correct, if not, some people are going to be real surprised when they come home from work.

ALEX strengthens significantly
Tropical storm Alex has strengthened dangerously over the past few hours and could become the first hurricane of the 2004 Atlantic Hurricane Season later on today. Reports from the hurricane hunter aircraft suggest maximum sustained winds have increased to near 60 mph with higher gusts. This is supported by a much lower minimum central pressure of 992 mb.
At 8 AM EDT, the center of tropical storm Alex was located near latitude 31.3 north, longitude 79.0 west or about 120 miles south southeast of Charleston, SC. Alex has been drifting eastward over the past few hours. A slow motion towards the north and or northeast is anticipated over the next 24 hours. On this track, the center of Alex will likely make it close to the coast of South Carolina and North Carolina later today, thus heavy rain squalls near the coast later today through tonight.
Maximum sustained winds are now up to near 60 mph with higher gusts. Expect additional strengthening over the next 24 hours and Alex could potentially become the first hurricane of the 2004 Atlantic Hurricane Season. Tropical storm force winds extend outward up to 105 miles from the center.
Minimum central pressure is now 992 mb or 29.29 inches as reported by the Hurricane Hunters. This is n 18 mb drop in central pressure since 5 PM EDT last night. Definitely some significant strengthening and the potential is for more strengthening. The watches and warnings remain the same this morning with Tropical Storm Watches in effect from South Santee River to Edisto Beach and from Cape Hatteras to Oregon Inlet. Tropical Storm Warnings remain in effect from Cape Hatteras southward to South Santee River. This could change and potentially even be upgraded if this system strengthens more than forecasted and strikes near the coast. Indications show this being more of a coastal issue as opposed to an inland threat at this time, which means dangerous rip currents, strong winds, and heavy rain squalls along the Carolina coast.
Winds could potentially reach hurricane force tonight for the North Carolina Outer Banks and especially over the offshore waters as Alex has a better chance of striking just offshore from North Carolina through Tuesday.

Each system has some different character and attitude towards it. But I wouldn't be surprised during this bursting phase that this system becomes the first hurricane of the 2004 Atlantic Hurricane Season. With less vertical shear combined with very warm Gulf Stream waters makes for a very dangerous mixture for this system as it continues to develop over a particularly dangerous areaof the western Atlantic, the gulf stream.
The best news is if this center remains of the Carolina coast. But it will be very close tonight into Tuesday

It's certainly a nice warm up to what could be a more active hurricane season as we continue through this year. As long as the projected path holds or even goes further offshore than progged and the Carolina coast could see little any anything except a few feter ban rain squalls and dangerous rip currents. Best bet is to stay off the water today through Tuesday as waves are higher than they were yesterday. Only minor impact is likely with respect to beach erosion and rain squalls. But certainly Alex looks more impressive this morning than it's ever been in it's life. After today, I suspect southwesterly shear will do it's thing and kill the intensification process of this system. This also means an offshore entity the way it looks now.

Latest loop
Appears that a NE move may be present. Question is this just a bump or a beginning.
