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.

It has been beautiful sunshine here in St. Aug for two hours now. No rain and not a leaf moving.

1. Did the storm fall apart before land fall?
2. Is it over now for St. Johns county?
3. I looked on radar and did not see anything very much.

NHC went from 60 to 65.

What am I overlooking?

Not to compare disasters or anything, but the funnel clouds in Florida are absolutely nothing compared to what we've seen on the blog the last couple weeks in Oklahoma. Too bad people that get hit by tornadoes don't have a few days advanced notice like hurricane victims do :(

Someday maybe we'll see more advanced notice on tornadic storms, and there already is a lot more notice than even 10 years ago.

1457. SLU
From CSU:

Most years do not have named storm formations in June and July in the tropical Atlantic (south of 23.5°N); however, if tropical formations do occur, it indicates that a very active hurricane season is likely. For example, the seven years with the most named storm days in the deep tropics in June and July (since 1949) are 1966, 1969, 1995, 1996, 1998, 2005, and 2008. All seven of these seasons were very active. When storms form in the deep tropics in the early part of the hurricane season, it indicates that conditions are already very favorable for TC development. In general, the start of the hurricane season is restricted by thermodynamics (warm SSTs, unstable lapse rates), and therefore deep tropical activity early in the hurricane season implies that the thermodynamics are already quite favorable for TC development (Figure 8). Also, this predictor’s correlation with seasonal NTC is 0.52 over the 1950-2007 period, and when tested on independent data (1900-1948), the correlation actually improves to 0.63, which gives us increased confidence in its use as a seasonal predictor.

Just something to keep in mind.

Subject: G7) Does an active June and July mean the rest of the season will be busy too?

...

However, as shown in (Goldenberg 2000), if one looks only at the June-July Atlantic tropical storms and hurricanes occurring south of 22N and east of 77W (the eastern portion of the Main Development Region [MDR] for Atlantic hurricanes), there is a strong association with activity for the remainder of the year. According to the data from 1944-1999, total overall Atlantic activity for years that had a tropical storm or hurricane form in this region during JJ have been at least average and often times above average. So it could be said that a JJ storm in this region is pretty much a "sufficient" (though not "necessary") condition for a year to produce at least average activity.

NWS Pueblo Colorado

While flying back from vacation on May 31st, I took this image of thunderstorms over central Oklahoma. The storm here was the supercell that produced the widest tornado recorded in U.S. history (2.6 miles), and, tragically, killed 20 people. This photo was taken shortly before the tornado formed. Note the extensive anvil as the storm reached the top of the troposphere, and the clouds overshooting the anvil into the stratosphere, indicating violent updrafts in excess of 100 mph. -Tom Magnuson, WCM NWS Pueblo - at north central Oklahoma at 40K feet.

Looks like alot of that dry air is getting sucked into the core of Andrea and drying out the east side. It appears the heaviest precip is now on the north side of the system.

If this continues, the flooding threat for Charleston will diminish greatly.

This is the key point about this impressive wave presence in early June.


Absolutely.

Quoting robj144:


Is there evidence that this will continue the entire season though?
Quoting PalmBeachWeather:
SLU.One storm does not make for a busy CV season.....Way too early


The thermodynamics (instability, SSTs, atmospheric heat energy) determine when the Cape Verde season starts and in hurricane seasons which have significant activity in the deep tropics in June and July, it indicates that the thermodynamics are already sufficient for development very early. This pattern always breeds major Cape Verde hurricanes during the business end of the season.

You don't even have to look far to understand this. In recent seasons with at least 1 tropical depression or strong Twaves in June in the deep tropics, those were all active Cape Verde years: Namely 2000, 2003 and 2010.
