ex-93L is a tropical cyclone IMO feeding off the nearby ocean and inland lakes/swamps..could be JULIA already with sustained winds of 40 MPH being reported offshore

 

been getting better organized all day...still moderate shear but all that is doing is causing the LLC to reform near the mid level center further east and closer to the coast/water

 

I bet lots of internal discussion at the NHC..how you you name a storm or declare it a depression when its over land and may  remain inland....do you declare it or not?

1012mb at ST Augustine.

For the North Atlantic...Caribbean Sea and the Gulf of mexico:

 

The National Hurricane Center is issuing advisories on tropical
storm ian, located well to the east-southeast of Bermuda.

 

Surface observations, satellite images, and radar data indicate that
an area of low pressure is located just inland near St. Augustine,
Florida.  This system continues to produce a large area of showers
and thunderstorms, with winds to tropical storm force along and just
offshore of portions of the northeast Florida coast. This system
has been maintaining its organization through the afternoon and
early evening, and advisories will likely be initiated later this
evening. The low is expected to move north-northwestward to
northward at 10 to 15 mph tonight, near and parallel to the
northeast coast of Florida. Strong gusty winds, some to tropical
storm force, will continue over portions of the northeast Florida
coast tonight, and heavy rains will continue to spread over central
and northern Florida tonight and Wednesday. Some areas from
northeast Florida to South Carolina could receive 3 to 6 inches of
rainfall with isolated maximum amounts of 10 inches possible. Please
consult your local National Weather Service office for additional
information on this system, including possible warnings.
* Formation chance through 48 hours...high...70 percent
* formation chance through 5 days...high...70 percent

New ECMWF has a pretty good 'cane by 240 hours, could be a threat.

GFS has something too at 240, albeit much weaker and less organized but looks to get swept out to sea with a front exiting the east coast. I have a vacation planned on the shore of NC starting the 24th so personally hoping this one doesn't materialize.

storm conditions are already occurring within the warning area.

For storm information specific to your area, including possible
inland watches and warnings, please monitor products issued by your
local National Weather Service forecast office.


DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 1100 PM EDT (0300 UTC), the center of Tropical Storm Julia was
located near latitude 30.3 North, longitude 81.6 West. Julia is
moving toward the north-northwest near 9 mph (15 km/h) and this
motion is expected to continue tonight with a reduction in forward
speed tomorrow.

Maximum sustained winds are near 40 mph (65 km/h) with higher gusts.
Some weakening is forecast during the next 48 hours. Little change
in strength is expected tonight.  Julia is forecast to weaken to a
tropical depression by late Wednesday.

Tropical-storm-force winds extend outward up to 45 miles (75 km),
mainly to the northeast and southeast of the center. 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 estimated minimum central pressure is 1009 mb (29.80 inches).


HAZARDS AFFECTING LAND
----------------------
WIND: Tropical-storm-force winds are already occuring within the
tropical storm warning area.

RAINFALL: Julia is expected to produce 3 to 6 inches of rain near
the northeast Florida, Georgia, and South Carolina coastlines
through Friday afternoon. Isolated totals of 10 inches are possible.
This rainfall could lead to flash flooding. Flooding may be further
compounded with persistent strong onshore flow reducing river and
stream discharges.

TORNADOES: An isolated tornado or two will be possible tonight
through Wednesday morning across parts of northeastern Florida and
southeastern Georgia.

GFS has it near the Carolinas in like 9 days. long ways out.  

The next disturbance coming off Africa is predicted to be a cyclone as well...possibly even stronger.

It would be nice to have something to track, given that its the peak of the season. It seems that the latter half of the season has been the more active one in the last few years.

All GFS runs for the past few days, and sporadic runs for days before that, have at least hinted at a wave traversing the MDR way down at 10 degrees or lower, which then organizes as it reaches the southern islands/south american coast.  The euro is showing something a bit farther north.  It's at least something to watch.

This wave coming off of Africa is pretty interesting later on down the road. GFS has been consistent showing something (TS/cane) in the GOM D10-14.. Other models generally agree on development of the wave, but differ on location, which should be expected this far out. Lots will change, so there's lots to watch.
