NHC begins advisories on Potential Tropical Cyclone

It did not take long to get the Atlantic Hurricane Season underway. On the second day of the season we now have advisories being issued on what will likely become Tropical Storm Alex by Friday. Wind shear continues to be an issue for this system and will continue to present a hostile environment over the next couple of days.

Large areas of convection have been bursting well to the east of the broad area of low pressure. The center appears to be forming closer to the northern tip of the Yucatan. The disorganized system with the lack of a well defined center presents a forecasting challenge for the various computer models to pinpoint the exact track. There continues to be a spread in the various model guidance because of the disorganized nature of this developing system.

There is a distinct possibility that we will see the center of this storm jumping around or reforming as it continues to evolve and move toward the Florida coastline. This will result in adjustments to the eventual track of what looks to become Tropical Storm Alex. The strongest portion, with the heaviest rainfall is the right hand side of the storm which still puts the strongest side of this storm over south Florida. Shifts in the track one way or the other could bring more rain over central Florida or lessen our rain coverage. South Florida could see between 4-8 inches of rainfall with isolated areas of up to 12 inches of rain.

The rainfall will begin to spread over the state on Friday and by the afternoon we could see some rain overspreading central Florida since much of this storm is displaced to the east. Saturday will be a wet an breezy day with torrential rains over south Florida. This will be followed by quick clearing and drier conditions on Sunday.

The sun setting over the Gulf and Caribbean this evening reveals the intense convection on the eastern side of this storm and a center beginning to form just north of the Yucatan peninsula.

Hurricane Season begins with Invest in Caribbean

Today marks the beginning of the Atlantic Hurricane Season. For the past couple of days we have been watching Hurricane Agatha in the Pacific make landfall and the remnants of that system add fuel into the western Caribbean. A broad area of low pressure in the western Caribbean has now been designated as Invest 91L.

Late day satellite imagery shows area of strong convection and a developing area of low pressure. The aircraft reconnaissance flight is currently schedule to fly down into this Thursday (6/2) afternoon to investigate the area.
Currently the National Hurricane center is placing a 70% of tropical development over the next 2 days and an 80% over the next 5 days. This is a common area for early season tropical development, but there is large amounts of dry air across the Gulf of Mexico and strong wind shear in the southern Gulf. These factors will limit any intensification of this system. It does not appear conditions will become very favorable for development until it moves past Florida and into the Atlantic.

The main impacts look to be at this time, heavy rainfalls across south Florida. The fine details of this forecast will become clear over the next 24 hours, but the exact track will determine how much rain and how far north will the rains reach. Gusty winds will be confined close to where this system moves onshore and highly dependent on how much development we see with what could become a Tropical Depression or possibly a Tropical Storm.

Rainfall will move over Florida beginning on Friday evening into Saturday and quickly clear out by Saturday evening.
