Tropical Storm Andrea hits Florida

Tropical Storm Andrea made landfall near 5:40 pm EDT in the Big Bend region of Florida as a tropical storm with 65 mph winds. Andrea had a busy day Thursday in Florida, dumping heavy rains, spawning ten tornadoes, and bringing a storm surge of up to 4.5' to the coast. While the Hurricane Hunters did measure sustained winds of 65 mph over the ocean shortly before landfall, very few land stations recorded sustained winds in excess of tropical storm force, 39 mph. Here are some of the higher winds measured at coastal stations:

A personal weather station at Bald Point State Park near Apalachicola had sustained winds of 46 mph at 10 am EDT.
Cedar Key had sustained winds of 40 mph, gusting to 50 mph, at 3:43 pm EDT.
Punta Gorda had sustained winds of 37, gusting to 58, at 1:04 pm EDT.
St. Petersburg topped out at 34 mph, gusting to 48 mph, at 10:23 am EDT.

Two sets of tornadic rain bands moved through West Florida on Thursday, one between 2 am and 5 am, and the other between 10 am and 3 pm, spawning a total of five suspected tornadoes. The first band produced two EF-0 tornadoes: one with 75 mph winds that hit Myakka City, damaging 3 homes and 10 other buildings, and one with 80 mph winds that cut throughout the heart of Sun City, causing minor damage. NWS damage surveys will be occurring Friday in Fort Myers, Venice, Clearwater, and Gulfport to check out the damage swaths of the other three suspected tornadoes.

The Florida East Coast was hit by five suspected tornadoes. Only one caused an injury, a tornado that hit The Acreage in Palm Beach County at 6:45 am EDT. Two other tornadoes were reported in Broward and Palm Beach Counties, and two more were reported in coastal areas near the Georgia border.

Here are the highest storm surge values as of 7:00 pm EDT:

3.2' at Tampa (at McKay Bay Entrance)
2.5' at Clearwater Beach (near St. Petersburg)
4.5' at Cedar Key

The Atlantic hurricane season is getting longer
Andrea's formation in June continues a pattern of an unusually large number of early-season Atlantic named storms we've seen in recent years. Climatologically, June is the second quietest month of the Atlantic hurricane season, behind November. During the period 1870 - 2012, we averaged one named storm every two years in June, and 0.7 named storms per year during May and June. In the nineteen years since the current active hurricane period began in 1995, there have been fifteen June named storms (if we include 2013's Tropical Storm Andrea.) June activity has nearly doubled since 1995, and May activity has more than doubled (there were seventeen May storms in the 75-year period 1870 - 1994, compared to 6 in the 19-year period 1995 - 2013.) Some of this difference can be attributed to observation gaps, due to the lack of satellite data before 1966. However, even during the satellite era, we have seen an increase in both early season (May - June) and late season (November - December) Atlantic tropical storms. Dr. Jim Kossin of the University of Wisconsin looked at the reasons for this in a 2008 paper titled, "Is the North Atlantic hurricane season getting longer?" He concluded that there is a "apparent tendency toward more common early- and late-season storms that correlates with warming Sea Surface Temperature but the uncertainty in these relationships is high." He found that hurricane season for both the period 1950-2007 and 1980-2007 got longer by 5 to 10 days per decade (see my blog post on the paper.)

Invest 92L in the Central Atlantic headed towards the Lesser Antilles
Satellite images show that a large and unusually well-organized tropical wave for so early in the season has developed in the Central Atlantic, midway between Africa and the Lesser Antilles Islands. The wave has a modest degree of spin and heavy thunderstorms. NHC designated this system 92L Thursday afternoon. High wind shear of 20 - 25 knots is ripping up the thunderstorms in 92L as they form, though, and wind shear is predicted to increase to 30 - 40 knots Thursday night through Monday, making development unlikely. The wave will likely bring heavy rain showers and gusty winds to the northern Lesser Antilles Islands beginning on Sunday night.

Apparently there's power out somewhere because the electric company called to say mine would be back on at 2 a.m. It's not off but that's good to know. :)

Husband called from work in Orange. Said he got to work while ago looked up and all he saw was a mass of gray and it started turning. He ran for the store. (Walmart) said he could hardly get in the door. Blew all of their outdoor things all over the place.

And this is going on now...

Geeze, that would be downright depressing if that happened again. We havent got "Hit" by a Tropical System since Ike (You could say we got hit by Hermine (2010) but it wasn't a "Landfall"). We need something...

Quoting MTWX:


Lowndes County was named after the late William Jones Lowndes, (1782-1822) he was from South Carolina and a U.S. Congressman and an earnest supporter of the War of 1812. Lowndes County in Georgia and Alabama were also named after him. Lowndes County was formed under First Constitution by act created on January 30, 1830.

How odd. It looks like Lowndes County MS, AL, and GA were all named for a Congressman from South Carolina....but there's no Lowndes County SC. I guess he had more friends further south than at home. :-)

I have to agree here. Since just prior to landfall, dry air has chewed her up. They are STILL sticking with the "heavy rain" forecast, but I honestly can't tell you why. I think 1" is being generous here. Really no more than a few sprinkles here and there. Our biggest concern are the isolated tornadoes. Beyond that, she dried up.


Yep, that dry sector is quickly approaching so unless another significant band somehow sets up in that dry area, then it is all but over here already.

The GFS ensembles do say pressures will begin to lower across the western Atlantic at the end of the month. This is when we'll probably have to start watching for our second named storm, assuming we don't get any frontal storms like Bret, Cindy, or Alberto before that time.

There are other warnings. All in the offshore waters.

That being said, not calling him Dr. when he's speaking as a professional in the field is quite insulting. You could disagree and still call him Dr.

Also, you need to learn how to quote. :) It's confusing because your response is in the quote, which looks like it's part of the quote. It tough to separate the two without looking back at the post you're quoting.

Naa, this is going to be a non-event for us. That 50 mph wind in the intermediate advisory is generous. It'll be down to 40 mph at 11, just enough to keep it a TS. Also, Andrea is racing NE now, and will be in North Carolina by noon tomorrow.

Let's remember from here on out Tropical Storm Andrea won't be feeding over any warm ocean waters, but will be maintaining its intensity through baroclinic processes. Who knows, it might even intensify slightly.

I wouldn't say killing Andreas since the pressure fell another mb between 5 and 8 p.m. You may get some very strong winds there as midnight approaches if the pressure stays steady or goes down another mb or two.

Once again, the very wet and broad area of low pressure depicted in several GFS runs in the long range is not Invest 92L. Our central Atlantic disturbance, low, depression/storm, whatever you want to call it, is likely to track west-northwest, north of the Leeward Islands, and slowly die in the process.

Between 5 and 8 p.m. Andrea's center moved 0.3 degrees north and 0.4 degrees east. I think it will stay inland but will be very close. Not shocked if it does go straight over Savannah and Charleston.
