Yesterday, the National Hurricane Center officially labeled the disturbance in the Gulf of Mexico as Invest 91L. Today is the official start of Atlantic Hurricane Season and 91L is starting to show more signs of organization.

The National Hurricane Center has given the low pressure in the Gulf a medium (50 percent) chance of developing in the next 48 hours. Lower wind shear is allowing this system to organize. The most likely scenario is that a short-lived tropical depression or storm will form. If this happens, the first name in this year's list is Arlene.

However, as this low tracks south, wind shear will increase, which will dampen any chances of further development into the weekend. The southward track also means that the center of this low making a Florida landfall is unlikely. However, the Sunshine State will continue to be lashed by tropical moisture through Saturday.

Flash flooding is a concern, especially in South Florida. At least 2-3 inches of rain is anticipated through the weekend, but some areas will see more. The National Weather Service has issued a flood watch for part of South Florida, including Miami and Fort Lauderdale, through Friday evening.

Weather & Radar's expert meteorologists will be keeping a close eye on the system. Right now, the WeatherRadar indicates that this low pressure will slowly move south through the Gulf into the weekend.

All eyes will be on this system, including those of the Hurricane Hunters. The Hurricane Hunters plan to begin flying into the storm today, with the first mission scheduled to depart at 1:45 p.m. ET. A second mission is scheduled to take off at 6:15 a.m. ET Friday.
