2PM EDT 8 June 2013 Update
This is just a quick update to note that the last official advisory on PT Andrea has been written by . PT Andrea is now racing out to the north-northeast, and almost all of the US-related weather is either soon coming to an end in Maine, or already well offshore. Atlantic Canada will still have a lashing before Andrea is finally absorbed by another low in about 48 hours, however.

8AM EDT 7 June 2013 Update
Tropical Storm Andrea is over South Carolina this morning and will briefly exit the coastline, rain ahead and to the east, with a long tail that reaches toward south Florida continues.
Another area of low pressure in the Central Atlantic, 92L, looked impressive yesterday for June, but has since weakened, we'll monitor it in case of any regeneration, but it will take days, if at all as it tracks generally westward.
Prior Update
Tropical Storm Andrea strengthened to a 60MPH Tropical Storm and is approaching the big bend of the area, heading north northeast at 14mph, bringing strong rainbands onshore in Florida bringing a few short lived tornadoes, and lots of rain.
Once it moves onshore other areas of the southeast will see some effects from Andrea, particularly those who wind up at or just south of where the storm's center passes. Tropical Storm Warnings are up from Flagler beach in Florida north to Virginia.
What is Andrea doing in your area, let us know here.
The strong rain bands have produced a few tornadoes, with some damage reported near Palm Beach west of 95.
Another very strong rainband is offshore and may be approaching Tampa later this morning.
Tropical Storm Andrea has defied forecasts calling for little or no strengthening, and has become a potent 60 MPH Tropical Storm, and this could be conservative. Additionally, while not forecast, some additional strengthening is actually still possible before landfall.
Andrea has managed to run into a zone of upper-level winds that are actually resulting in two events supportive of intensification:
First, strong upper-level winds that would normally be creating detrimental shear are running in about the same direction Andrea has been traveling overnight, also important that her forward speed has increased, both resulting in net effective shear that is actually quite a bit lower than would be the case if the cyclone was heading to a more right angle of the mean upper-level flow.
Second, these same upper-level winds have created a nice source of exhaust for Andrea's thunderstorms, thereby creating a perpetual entrainment machine: inflow in, inflow out (vacuum) more inflow in, more inflow out (rinse and repeat).
Andrea now exhibits the hallmark of a tropical cyclone that does not necessarily need to reach hurricane status to result in more than just some heavy tropical squalls, and those in its path may wish to consider revisiting their hurricane preparedness plans, as regardless of whether Andrea intensifies further, very heavy rain - with increased risks of inland flooding - some storm surge flooding along the coast, potentially damaging winds - especially in gusts - and isolated tornadoes, are now all possible anywhere from south Florida right up into the Big Bend.
Later in the week, Andrea is forecast to continue at storm intensity as she rides up the east coast. This has necessitated Tropical Storm Warnings to be extended all the way to Virginia.

Wanted to mention a few webcams on the West coast of Florida as a big rainband is approaching.

Based on radar, it looks like Andrea is keeping east of the official track, and still fairly strong for a tropical storm.

Pretty amazing how fast Andrea spun up, I was shocked at the radar image this AM. Never thought I see spiral bands, figured it would just continue to be a blob that kind of floated over NW FL. I've seen references to tornados in Broward and Palm Beach but can't find any stories online confirming if/where they hit.

Apparently Andrea is still strengthening. RECON just measured 990mb and peak flight level winds of 70 knots. That reduces to about 70 mph at the surface.
990mb would equate to an 85 mph storm under normal conditions.

24 hours ago the picture was a vigorous low level circulation with numerous tightly wound spiral bands of low level clouds and no convection. About sunset last night the convection at the center and in the feeders began to take hold and the process began...

Interesting to note that at 19Z, the satellite presentation still shows a firm low level circulation albeit with limited convection. However, the radar images out of Tallahassee suggest that the center has weakened and expanded. The satellite location was about 50 miles due west of Cedar Key and movement seems to have again shifted to a more northerly course.

NHC just posted an update at 5:45pm - winds now sustained at 65mph.
Here are ship reports. Nothing anywhere near it though - closest ones are over 50 NMs away: http://www.ndbc.noaa.gov/radial_search.php?storm=at1
Keep an eye for tornadoes. Currently 2 tornado warnings on the SE Georgia coast.

Andrea's structure is subtropical with everything well away from the center and has been since day one. Any strengthening was likely due to some baroclinic processes as Andrea is interacting with the upper level trough immediate to its west. Wind shear analysis clearly show Andrea being sheared aloft at this time.

2 tornado's confirmed by the EMS in Fernandina Beach, Georgia State trooper just called in one along I 95 in South Ga. Were reports that they were water spouts at first but changed to Tornado's shortly after by spotters.
