The tropical low pressure which we have been tracking over the last 24 hours… which moved from the Bahamas to across coastal eastern Florida… has now become a tropical storm along the northeastern Florida coast.
Maximum sustained winds are around 40 mph… with higher gusts. The storm is moving to the north/northwest around 9 mph.
At 11pm the location of the storm was about 5 miles west of Jacksonville, Florida and about 50 miles south of Brunswick, Georgia.
A tropical storm warning is in effect from Ponte Vedra beach Florida to the Altamaha Sound Georgia. This includes Glynn and Camden counties in our local area.
The storm is expected to produce very heavy rainfall over northeast Florida… Georgia and south Carolina over the next 24 to 48 hours. Storm totals through Friday afternoon are likely to be widespread 3-6 inches with isolated totals of 10 inches.. which could lead to flash flooding.
Recent observations indicate that sustained tropical-storm-force winds are occurring along the northeast coast of Florida from Ponte Vedra northward to the mouth of the St. Johns River.
The storm will move into southeast Georgia overnight into Wednesday morning… then slow down its forward motion as it weakens into a tropical depression later Wednesday. The storm will then weaken to a remnant low by Thursday but is forecast to remain nearly stationary over southeast Georgia Wednesday Night into Thursday Night… creating a concern for locally heavy rainfall.
In addition… isolated tornadoes can’t be ruled out over northeast Florida and southeast Georgia tonight and Wednesday morning.
With Julia having an impact on our local weather.. here are a few things you can expect from the storm.
- Main concern is the heavy rainfall. Widespread 3-6 inch storm totals along the coast and along the track of the storm. Look for the storms totals to fall from tonight through at least Thursday night… possibly into Friday before the storms weakens/dissipates/ejects out.
- Gusty winds… primarily overnight into Wednesday along the coast. Wind gusts could reach up to 40 mph Wednesday along the coast of Tybee and Hilton Head. Further south in the tropical storm warning area… winds could briefly gust to 50 mph tonight into tomorrow morning in Glynn and Camden county.
- Surf could pick up to 3-5 feet Wednesday…. and there will be an enhanced risk of rip currents.
- Isolated tornadoes are possible overnight and Wednesday morning over southeast Georgia. Tornadoes are not likely across the Low Country of South Carolina.
- It is possible if heavy rainfall occurs around high tide… combining with brisk onshore flow… that minor coastal flooding occur. This is again most likely around the time of high tide… which at Fort Pulaski runs at 7:18am Wednesday morning and 7:50pm Wednesday evening.
- Isolated power outages are possible… especially near the coast where the gustiest winds will occur Wednesday.
