Felix Strengthens into a Category 3 Hurricane while Passing to the North of Aruba...Felix Forecast to Impact Central America or the Yucatan Peninsula as a Category 4 Hurricane on Tuesday and Wednesday...Low Pressure Center off the Georgia Coast Moving Slowly Eastward...Heavy Downpours Possible in North and Central Florida on Sunday Afternoon and Evening...Tropical Wave in the Central Atlantic Ocean Remains Disorganized...

At 2 PM EDT Sunday, the eye of Category 3 Hurricane Felix was located about 100 miles to the northwest of Aruba, or about 1,170 miles to the east-southeast of Belize City, Belize. Maximum sustained winds have increased to near 125 mph, and Felix continues its brisk west-northwest pace around 18 mph. Tropical storm watches are in effect for Jamaica, but Felix is forecast to pass well to the south of Jamaica and the Caymans on Monday and Tuesday.
A ridge of high pressure is forecast to remain to the north of Felix during the next several days. This feature steer Felix on a west-northwesterly course through mid-week. The official forecast strengthens Felix into a Category 4 hurricane on Labor Day before the cyclone threatens Central America, Belize, or Mexico's Yucatan peninsula on Tuesday and Wednesday. Felix is not a threat to Florida during the next 5 days, but this hurricane may enter the southwestern Gulf of Mexico later this week after interacting with land. Please visit the National Hurricane Center for the latest information on Felix.

A low pressure center has developed off the Georgia coastline along a stalled frontal boundary that extends westward across north Florida. The low pressure center off the Georgia coastline may slowly develop into a tropical depression during the next few days it drifts eastward over the warm waters of the Gulf Stream. Weak steering currents could cause this system to move erratically off the southeastern U.S. coast.

The stalled frontal boundary will once again fuel the development of scattered thunderstorms across north and central Florida on Sunday afternoon and evening.

Elsewhere in the tropics, thunderstorm activity associated with a tropical wave located in the central Atlantic Ocean about 1,400 miles to the east of Barbados in the Windward Islands has not become any better organized today. Easterly wind shear and dry air aloft in the vicinity of this wave should prevent significant development during the next 24 hours. There is some potential for slow development later this week as this disturbance moves slowly westward through the central Atlantic Ocean.

Update: Felex is now a cat 4, go to Jeff gammon's site to checkout the latest updates!!you can find to right of my page also dewdrop is again doing a fantastic job with her forecast

HAIL (3/4 inch or greater)

Hail can cause significant damage to your vehicle, break windows and damage roofs of homes and businesses.
Hail can cause significant bodily injuries such as broken bones and even blindness if wind blown.
Softball (4.5 inches) sized hail was reported in Lake Wales, Florida on March 30, 1996.
Haildrifts, up to four feet deep of dime to nickel sized hail, occurred in low-lying areas near Zephyrhills, Florida on January 29, 1997.
Hailstones the size of softballs can fall at speeds faster than 100 mph

supercell

Supercells derive their rotation through tilting of horizontal vorticity (an invisible horizontal vortex) caused by wind shear. Strong updrafts lift the air turning about a horizontal axis and cause this air to turn about a vertical axis. This forms the deep rotating updraft, the mesocyclone.
A cap or capping inversion is usually required to form a downdraft of sufficient strength. The cap puts an inverted (warm-above-cold) layer above a normal (cold-above-warm) boundary layer, and by preventing warm surface air from sinking too far, allows one or both of the following:
Air below the cap warms and/or becomes more moist
Air above the cap cools
This creates a warmer, moister layer below a cooler layer, which is increasingly unstable (because warm air is less dense and tends to rise). When the cap weakens or moves, explosive development follows.
In North America, supercells usually show up on Doppler radar as starting at a point or hook shape on the southwestern side, fanning out to the northeast. The heaviest precipitation is usually on the southwest side, ending abruptly short of the rain-free updraft base or main updraft (not visible to radar). The rear flank downdraft, or RFD, carries precipitation counterclockwise around the north and northwest side of the updraft base, producing a "hook echo" that indicates the presence of a mesocyclone.
