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.

This was a very fast moving storm with very gusty winds, heavy rain but over within minutes. Phew!

Hope everyone who has stormy weather out there stays safe!


Wow! So glad it wasn't worse for you!

Wow! Glad you're safe. They were some nasty storms. As you say fast moving. Mom and Dad were caught on I10 coming back from Beaumont and said traffic came to stand still because the rain was so hard no one could see anything. They had some lawn furniture tossed around when they got home. Down to just a drizzle here. Still here thunder rumbling in the distance though.

Right off Florida, although north of and clear of the Bahamas. The GFS model has a low which suddenly appears over the NE part of Florida at 150 hours and then again at 240 hours with no indication how it got there, so I don't know how much faith to put in it. However, the BAMS and LBAR don't want to kill off 92L and want to send it up your direction. I guess, within 48 hours, it will be dead or starting to a trip to the Bahamas.
I did note the BAMS track. Only consolation is that it IS the BAMS [and I am convinced LBAR is only there for the laffs] which means anything that does arrive is likely to be more on the TD or Twave end as opposed to a more organized storm. However, given we've already had round one and round two of torrential rains here, I'm not sure New Providence will be much interested in a vigorous Twave any time soon...

It probably was this morning, and was likely a tropical depression two days before that. I've been tracking it consistently since it left the coast of Africa:


I was impressed by that tropical wave since it rolled off of AFrica...quiet impressive for June. Here is a summary of my observations on it I made in my blog posts:

JUNE 1
.A tropical wave rather impressive for the month of June is rolling off of Africa with a 1010 mb low pressure spin and organzied t-storms. Based on the symmetry of cirrus outflow streaks in all quadrants of the t-storm activity...I would say their is a supportive outflow enhancing and shear reducing upper ridge directly overhead that could seemingly aid in this tropical wave's development. However...climatology...lack of computer model support (as of 18Z)...and an eventual westward track toward the shearing paragraph P3 upper trough suggest that tropical cyclone development here is not likely at this time.

JUNE 4
Tropical wave SW of the Cape Verde Islands in the previous discussion is now entering the waters midway between the Lesser Antilles and Cape Verde Islands. It is entering a jet of shearing upper westerlies on the north side of low-latitude eastern Atlantic upper ridge and in advance of paragraph P8 upper trough.

JUNE 5
Tropical midway between the Lesser Antilles and Cape Verde Islands seems to have become enhanced a bit in the last 24 hours by low-latitude eastern Atlantic upper ridging. However it will be entering a jet of shearing upper westerlies on the north side of the low-latitude upper ridging and in advance of paragraph P7 upper trough.

JUNE 6
Tropical midway between the Lesser Antilles and Cape Verde Islands still seems to be enhanced by low-latitude eastern Atlantic upper ridging. However it will be entering a jet of shearing upper westerlies on the north side of the low-latitude upper ridging and in advance of paragraph P7 upper trough.

The National Hurricane Center doesn't like designating anomalies, regardless of whether those systems met the criteria of a tropical cyclone at the time. They did the same with, coincidentally, Invest 92L in the central Atlantic in June 2010.

92L will likely be the one that got away... I don't see it being called in the post-season either, the NHC goofed and it really didnt matter if they called it or not because it's impending death in the shear was set in stone Named or not.

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.

I was in Cedar Key when the storm was making landfall. A 41mph sustained wind was recorded. Lots of the roads were underwater. There was 2 feet of beach erosion. Power lines were down and some homes were flooded. Waves were crashing over ther road spraying water 30 feet high.

Is Andrea going more ENE, favoring a reentry into the coastal Atlantic vs staying inland?

I clearly have no clue but, from watching the general movement over the last 12 hours or so, I think ex-Andrea is going to stay well inland, at least until somewhere around the Virginia coast. I've been remarking all day that Andrea seems to be a more northerly path than the models depct.

There doesn't seem to be another system out there except 92L that's capable of producing a low off north Florida in 10 days as far as I can tell. If the CMC picks this up as well, it might get real interesting.

The pressure keeps going down. I am beginning to think we will have a very nasty extratropical storm up here with a pressure of 985-990 as it goes by.

Yeah it was probably a TD, too bad it wasn't designated. May be a sign of things to come down the road.

Also, does anyone else have GRLevel3? Because I have that, along with Analyst, and the base reflectivity has been showing up blank for a couple days now and the info bar is gone. All the other modes work however and I don't get it. If anyone else has this problem or knows an answer to it TIA.

It's more than likely staying inland. It has continued a NNE or NE motion

Just came back from Clearwater Beach at Pier 60, had a blast getting sand blasted, the winds were strong, and the waves were high. I see that Andrea made landfall 40 miles NNW of Cedar Key and strengthened a little bit more, darn so close to where I predicted landfall.
