Andrea Intensifies to a 60 mph Tropical Storm, Spawns 5 Tornadoes in Florida

Tropical Storm Andrea has exceeded expectations. An Air Force hurricane hunter plane flying through Andrea near 3 am EDT found that a strong band of heavy thunderstorms with moderate turbulence and intense lightning had wrapped partway around the center, and Andrea had intensified into a respectable tropical storm with 60 mph sustained winds and a central pressure of 997 mb. The intensification occurred despite the presence of a large area of dry air to the storm's west, and high wind shear of 25 knots. Satellite loops show that Andrea has expanded in size this morning, and its heavy thunderstorms have become more intense. The heaviest thunderstorms were in a band well away from the center, extending from Tampa southwestwards over the Gulf of Mexico. There is a large slot of dry air behind this band, and Andrea may be able to close this intrusion of dry air off early this afternoon, and build additional heavy thunderstorms near its center. However, given the continued presence of dry air and increasing wind shear, and little time before landfall, it will be difficult for Andrea to reach hurricane strength before landfall occurs early this evening--though I won't rule out intensification to a 70 mph tropical storm. Heavy rains of 3 - 6" that have the potential to cause flash flooding will be the storm's main threat. Carrabelle, near Apalachicola, reported 4.5" of rain in a 5-hour period ending at 8 am EDT. Tornadoes in some of the heavier thunderstorms in Andrea's spiral bands are also a concern, and the storm had already spawned five tornadoes as of 9 am EDT. Bands of heavy thunderstorms with embedded rotating thunderstorms capable of generating tornadoes where over both the west and east coasts of Florida between 6 am - 8am, triggering tornado warnings in the counties near Fort Lauderdale and Tampa Bay. A tornado hit The Acreage in Palm Beach County at 6:45 am EDT, injuring one person, damaging homes, and downing trees and power lines. Two other tornadoes were reported on Florida's east coast, one in Broward County, and one in Palm Beach County. Andrea also spawned two tornadoes southeast of Tampa Bay between 2:30 am and 4 am EDT Thursday, but damage was minor. Most of South and Central Florida are under a tornado watch today. A storm surge of 2 - 5 feet is predicted for Tampa Bay northward to Apalachicola, and rip currents will be a risk for swimmers who brave the high surf. As of 9 am EDT Thursday, our wundermap with the storm surge layer turned on was showing storm surge levels just over 1 foot near Tampa and Apalachicola on Florida's Gulf Coast.

We won't have any new wind measurements from the Hurricane Hunters until about 3 pm EDT. Buoy 42036, 122 miles west-northwest of Tampa, reported sustained winds of 40 mph, gusting to 51 mph, between 7 am - 8 am EDT, when the center of Andrea was located about 60 miles to the south-southwest. Winds at a personal weather station at Bald Point State Park near Apalachicola hit 39 mph at 9 am EDT. Winds at Cedar Key were sustained at 28 mph, gusting to 34 mph, at 8:33 am EDT.

Andrea's place in history
Andrea formed in a typical location for early-season storms. The Gulf of Mexico, Western Caribbean, and Bahamas are the usual areas for the genesis of June tropical storms. Andrea's formation date of June 5 is over a month earlier than the average July 9 date for formation of the season's first named storm. On average, the Atlantic sees one June named storm every two years. In 2012, we'd already had two named storms by this point in the season--Alberto and Beryl. This year is the second time a storm named Andrea has appeared in the Atlantic. The previous incarnation, Subtropical Storm Andrea of 2007, wandered off the U.S. East Coast in May, and never made landfall. The 2013 version of Andrea is highly unlikely to get its name retired, and we'll be seeing a third coming of the storm in 2019.

Yeah, it's always a little tricky using the first storms of the season as somehow indicative of the rest of the season. I took delivery of my first new to me sailboat on August 15, 1992. Took her out for few days and tied back up in Nassau, congratulating myself on buying in a year with no hurricanes. Flew back home an August 21. My boat insurance payment book was in the mail when I got back. Got a phone call on August 26 letting me know my boat had come loose from its moorings, was swept out into the shipping channel, and was now was a hazard to navigation, since the top 6 feet of the mast was still above water. Hurricane Andrew, the "Big One", from one of the slowest seasons ever. My insurance agent did say I held the record for the shortest time from the first payment to a total loss. :-)

Was just wondering why they are re-using this name...???
From Wikipedia:The name Barry has been used for five tropical cyclones in the Atlantic Ocean.

Hurricane Barry (1983), approached Florida as a tropical storm, weakened to a depression before crossing, strengthened to a hurricane after exiting into the Gulf of Mexico; struck Mexico, causing some damage

Tropical Storm Barry (1989), dissipated in the mid-Atlantic without threatening land

Tropical Storm Barry (1995), formed off South Carolina then moved north, making landfall on eastern tip of Nova Scotia, causing no damage

Tropical Storm Barry (2001), made landfall in Florida, causing two deaths and $30 million in damage

Tropical Storm Barry (2007), short-lived tropical storm that made landfall in western Florida

The name Barry has also been used for one tropical cyclone in the Australian region.
Cyclone Barry (1996), Category 3 severe tropical cyclone (Australian scale)
 


It has yet to be used in a tropical cyclone worthy of retirement.

I am retired from storm chasing. Back in March, I left the USA and will not return. I now live directly under the ITCZ, which is both ironic and wonderful.

The loss of Tim Samaras, his son, and Carl Young really shocked me. They were some of the most cautious chasers out there.

I was fortunate in my chasing adventures. I never even received a scratch.

So now my efforts are part of history. I was the 1st to live stream a hurricane event (Hurricane Earl - 2010) and unfortunately or not, instructed others on how to do the same thing.

The best way to bring others into a landfall event of a hurricane and show the relentless nature of these storms is by live streaming. It is also a good way for more storm chasers to meet their maker. All it is going to take is the landfall of a monster Cat 5, and we will likely be told of more storm chasers being killed.

So to those live streamers I know...and to those I do not know...may you get through your adventures as I did...without even a scratch.

Yes, quite a well organized system. Although it was only a 65 MPH TS, it looked like a mature hurricane.

It pretty much has not stopped raining all day in Melbourne, FL. At 8am the rain was so loud on the roof that it woke me from a dead sleep. Of course, we have had lots of rain for the last week anyway, but it all seemed at least loosely tied to this storm.

We also had a tornado warning earlier today, so I arranged my interior closet and coaxed my parrot into his travel cage. He doesn't like sitting in the closet, but he will get over it.

Another season and another fascinating storm to mull over. Was concerned about the tornado threat for FL last night and this morning and it seems we have had plenty of them. Carolinas must be on alert tomorrow for these threats.

Andrea has dealt with alot but still intensified under moderate shear and an almost decoupled structure. Doesn't bode well for the next 4-5 months but every storm had its own character. The thermodynamics kept this thing rolling along...aided by the fact that the mid level circulation has been very robust throughout its life.

There will be some rough times ahead - we all hold out hope that they come in the form of 20 "fishies" rather than 1 major landfall. That strong disturbance out in the CATL is the first clue to what we are facing.

Prayers to those under tornado, wind and flood warnings from our first storm. And please - turn around, don't drown.

Hey, you!
