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.

Also an almost complete lack of street lights...and I mean anywhere. I don't know if the people of South Carolina don't like lights or hate paying electric bills but driving on a freeway in South Carolina at night with poor visibility is downright dangerous. The fact that most of the off ramps only have one sign marking them only makes things worse. Oh, and the paving. Man, talk about getting fillings knocked loose. I felt like I was in a third world country...and that's before I saw Pedro. :-)



Really? I hadn't noticed, seems normal to me. (kidding)

Sure it counts. How much rain have you had? I had five inches in the last two day in Alabama without a tropical storm. I was thinking of the supposed 15-20" forecast of several days ago.
It all fell before Andrea was named.

That's how we were getting it the last 10 days... I'm glad for the cloud cover and breeze that have been keeping temps and humidity down, but gladder the rain has stopped.

You made that up, right? Why will Andrea become a larger and more dangerous storm than it has already become? Andrea has not turned out to be an epic rainmaker anywhere. I hope the media is not hyping this up into another Sandy.

So, I've had an INCREDIBLE afternoon. Arrived in Ft. Lauderdale around 1pm... and got to the apartment around 1:45pm.

Everything was quiet weatherwise until about 4:30pm, when these mini supercells started forming a few miles inland from the beach I am staying on.

One of these mini supercells produced this brief funnel:



All of the supercells then congealed, and formed an extensive line all along the east shore of south Florida. Produced extensive lightning (one of which destroyed a transformer, seeing the explosion with my own eyes) and torrential rain 60mph gusts (mind you, I am about 450 feet above ground, so winds were definitely stronger than at the surface).

As the MCS then moved offshore, the storm had weakened slowly, but then, RIGHT at around sunset, the sun peeked out for about 5 minutes, and I just happened to look out the window to see THIS:



An incredible double rainbow with a pink background.

This has been an incredible start to my stay in Miami. 4 more days to potentially see storms!

I been thinking we'll see the centre out over the ATL somewhere between Savannah and St Mary's but that's just my opinion. Likely it'd still be a TS, too.

Concise analysis...
1-Andrea will continue as a storm crossing North Florida during the night, continuing on through the East coast of the United States, and it should lose its tropical characteristics between Friday and Saturday.
2-Invest 92L - winds of the Jet stream will influence on the circulation of this tropical disturbance. While models bring the low pressure near PR, do not pay attention to it for the moment, a trough will protect us with high windshear, and this wave should then weaken or fracture while it runs northeast of PR. However there will be rains in our environment associated with the field of moisture from the system.
3 - Prognosis of PR-take out your umbrellas. We return to the pattern of Sun and rain, with a weak area of moisture that is East of the Antilles, and enters with groups of clouds and rains come Friday and Saturday. On Sunday we receive moisture from the tropical disturbance that was just mentioned.


And there we go, did a grammatical error check. That is an awesome translator.

Gracias por la informacion.
Casi nadie escribe en espanol aqui.
Bastante de nosotros hablemos cuando se necesita, pero normalmente es cuando hay tormenta cerca de lugar hispano...

Some of us do, but mostly when there's a storm near a spanish-speaking area.

It's considered polite to translate to / from Spanish for yourself if possible.

I'm suprised. After a storm forms, the blog normally moves to something else. With Andrea, we waited until it made landfall.

3-Pronostico de PR-Vuelva a sacar el paragua. Volvemos al patron de Sol y lluvias, con una debil zona de humedad que esta al este de las Antillas, y entra con grupos de nubes y lluvias entra viernes y sabado. El domingo recibimos la humedad del disturbio tropical que le acabo de mencionar.
