Tropical Storm Andrea Tracking

TS Andrea, the first named Atlantic storm of the season continues to organize, but so far has only maximum sustained winds of ~60mph. Florida will get quite a bit of rain in addition to winds. The real issue will be what happens after it crosses the Florida peninsula and re-emerges in the Atlantic. Right now tracking models suggest it will be hugging the coast closely, which will prevent much strengthening.

    Typo alert; … “Florida will get quite a but of rain in addition to winds.”

    We are used to being the butt of jokes however. :-)

    I have to drive through that mess to Daytona in a few hours. Thanks for the update.

    REPLY: Typo fixed, thanks, Anthony

  2. Dennis Hand says:

    I live about 25 miles north of Tampa. We’ve had drought conditions here in Florida for the last several months, to the extent that the water nazis have tightened up on the restrictions, so the rain is welcomed.

  3. Janice Moore says:

    Take care, Mark Stoval.

    I just prayed for a safe journey for you. I hope God says, “Yes.”


    Thanks, A-th–y, for the great visuals. This website is SO COOL!

    Let’s see if the McKibbernaut clears its throat.

  5. Goode 'nuff says:

    Southeast farmers/Alabama farmers especially, really need rain. Radar looks like they’re getting some. Much of the upper Midwest region has had flooding and are dealing with replanting.

  6. Been trying to track down any evidence that urban aerosols steer hurricanes either away from or towards urban centres. But just lots of wacky government conspiracy stuff.

    It’s well establish urban aerosols decrease hurricane intensity by quite a large amount.

    I think urban aerosols steer hurricanes towards urban centers. So the effect of reduced urban aerosols is more intense landfalling hurricanes which are less likely to hit urban centers.

  7. Stephen Richards says:

    That’s not a storm. The UK gets 40 mph on an average day. Anything for a name that mob.

  8. MattN says:

    Up to 60mph this morning…

  9. Ric Werme says:

    About the absolute worst thing a tropical storm, tropical depression, or even remnants of one can do is stall. That brings a reminder that wind damage is worst on the coast and gets most of the video attention from reporters in the storm, but that inland flooding can be devastating too.

    Fortunately, it looks like Andrea won’t be hanging around anywhere.

    About the second worse thing it can do is merge with an extratropical storm. While New England and the mid-Atlantic area will have a brief encounter, it may be interesting as we have a storm to interact with.

  10. Ric Werme says:

    The water vapor image for the Gulf of Mexico shows a lot of dry air to the west of Andrea. Had this been a real hurricane, it would strangle the storm in hours. See


    Poor thing really has no chance at greatness. I’m impressed it’s as strong as it is.

  11. Gail Combs says:

    It is certainly keeping the temperatures cool here in mid NC (presently 66F @ 8:00am) We are already getting a bit of rain. Very welcome.

  12. Frank K. says:

    Yes – rain is good! Thank you, TS Andrea.

  13. philjourdan says:

    I hope it takes the western route. We can use the rain.

  14. Owen in GA says:

    Here in my part of Georgia, we have had a fairly normal rainfall year, but the lakes could use a large dose of tropical moisture to get back to full pool from the droughts of the last few years. I hope it takes the north and west part of the track and gives us a few inches.

  15. Caleb says:

    As long as they don’t get too strong, or stall, these weak tropical storms are very helpful when it comes to avoiding drought, when the summer sun is at its highest and evaporation is at its greatest. The worst drought I can remember in New England, peaking roughly in 1966, was largely due to a complete lack of dead and dying tropical storms passing over New England. That drought got so bad that Quabbin Reservoir, (Boston’s primary water supply,) sunk down to a level where cellar-holes in Greenwich, a town that was disincorperated and drowned when the reservoir was created, reappeared.

  16. Tom Trevor says:

    As we are right on the coast down here in Sarasota, I’m not sure hugging the coast is good thing. We need some rain, but we don’t need a flood.
    Oh just as I typed that it stopped raining (for now).

  17. beng says:

    Oh no, tropical rain in June?

    We’re doomed, I say. Dooooommmmeeeed.

    I don’t see how it’s holding together at all with the dry air to the west.

  19. JohnWho says:

    I am just south of Tampa Bay.

    Lots of rain and winds mostly less than 30-40 mph so far. We, too, needed rain, but not this much in so short of time.

    Coastal flooding along Tampa area will probably occur later near local high tide around 6:30pm today.

    Looks like it will bring rain to most of east coast of US over next few days or so. As long as it doesn’t strengthen, that would probably be good.

  20. Russell Klier says:

    NEATO!…Sarasota is getting some much needed rain…I have recorded about 0.75 inch today and about 1.5 inches the previous few days.

    Whatever you call it, it’s heading your way!

  24. Michael Jankowski says:

    It’s a “storm” of some sort…it’s spawned some tornadic damage and flooding. That’s not an average day in the UK.

    There’s always lots of bluster about hurricanes and tropical storms, and they certainly can be stressful, harmful, and damaging. But they are part of the water cycle for FL and portions of the SE US. If those events went away, it would be a bad thing for the water balance.

  25. James at 48 says:

    Tropical storm or cut off low?

  26. James at 48 says:

    Given the track I am failing to see how this could have started out as an Easterly Wave / ITCZ related event. If it is not related to these mechanisms it is not a Tropical Cyclone.

  27. OssQss says:

    Well down here in Bradenton, just south of Tampa, we have had just under 4″ of rain and a gust to 21 MPH on my home weather station since midnight. All is well aside from the power flickers that killed my AC air handler motor and network connectivity ( just replaced the APC battery but did not re-install it yet,,,, lesson learned). Back up hurricane kit portable AC system works just fine in real world testing however. Just a half dozen tornado, radar, signatures within a few miles this AM, but no damage. Some areas have had some damage from the EF0-EF1 possible touch downs.

    Just another day in paridise {sarc}

    Good to see Gail Combs back online with us! You have been MIA >

    ” Just a half dozen tornado, radar, signatures within a few miles this AM, but no damage. Some areas have had some damage from the EF0-EF1 possible touch downs. ”

    We had what appears to be one of these small tornadoes touch down briefly about 7/10 of a mile from my home in Venice. Some trees down on roofs and cars. Not so bad unless it was your house or car that got damaged. Lots of rain but as others here in Florida well know, it is always needed and part of the water cycle.

  31. eyesonu says:

    Anthony, thanks for the link to the NHC bulletin. In part it reads:


    My question is in this bulletin it would appear that the surge would be that above the normal tide level at the time. If I am correct in this then why would the storm surge with regards to TS Sandy at The Battery in NJ have been measured from the low tide level and the stated/claimed storm surge included the effect of high tide as well as a full moon which added several feet to the claimed surge? Where am I missing something? Or do I see it clearly?

    Hopefully this bulletin is presenting conditions correctly as per my understanding and there was simply a minor error of several feet with regards to Sandy.

    Given the track I am failing to see how this could have started out as an Easterly Wave / ITCZ related event. If it is not related to these mechanisms it is not a Tropical Cyclone.

    Can you check the definition of tropical cyclone? I don’t think there’s any requirement about easterly waves or such whatnot. While that’s what the big Cape Verde hurricanes do, all you need for development is warm water, convection, some spin, and low shear.

    A tropical storm is differentiated from an extratropical storm by a warm core (due to sinking air in the eye) and no frontal structure. I.e. the heat engine is vertical, driven by convection as opposed to horizontal, driven by cold air from poleward and warm air from the subtropics.

    Early season storms tend to form in the GoM and Carribean, the Cape Verde waters are too cool now.

  38. eyesonu says:

    I think it’s time to say “good bye Andrea”. Her 15 minutes of fame seems to be over.

  39. Gail Combs says:

    Her 15 minutes of fame maybe over but the east coast of the USA got a nice wetting. Always welcome in June, July and August when water shortages are a possible problem.

  40. P Walker says:

    Well , the tornado warning for our area just expired but other cells and rain are possible through the night . We are also in the projected path for Andrea with strong winds predicted later . Unfortunately my house is surrounded with some large pines – none of which are on my property – that might topple if we get much more rain and strong winds .

  41. benfrommo says:

    Lots of well needed rain here in Northern Florida, but not much else. No tornadoes, etc. The storm is rather nice. The only thing I kind of wonder about is whether this year might be bad in terms of tropical weather. Looks like the last big band is about to leave this area now so its all looking good.

  42. Peak determined sustained wind so far is 65 MPH. did explain that this is the probable maximum sustained wind anywhere at surface level in the cyclone. Explained in other sources is that “sustained” in USA is defined as average for 1 minute. The official altitude for measuring or determining this is 10 meters above the surface.

  43. DGH says:

    Due respect to the “don’t believe the hype” crowd, any action out of the east will exacerbate the the situation from which we are still recovering.

    The Northeast isn’t exactly prepped for yet another Nor’easter. This won’t be devastating. But plenty of folks will suffer yet another setback on the road to recovery from Sandy if this storm drops a few inches of rain and stirs up the surf as is currently forecast.

  44. Half Tide Rock says:

    In New England and watching the track carefully. In the fall lows often intensify rapidly as they come across Cape Hatteras and get into the warm water of the Gulf Stream. Right now it is tracking West of the Gulf Stream over cold water.. This is good. In another post there is a significant warm temperature anomaly shown off Cape Hatteras. The water is warmer there representing potential energy. I am inclined to watch what happens to the track alignment and the Gulf Stream before I discount the possibility of it surprising us..

    > I don’t see how it’s holding together at all with the dry air to the west.


    What I see in that video loop is the storm changing into an extratropical type storm.

  46. Janice Moore says:

    @ Mark Stoval — Did you make to Daytona okay?

  47. William McClenney says:

    Interestingly, it looks to be tracking NE faster than it’s rotation. Offshore to Hatteras warm water accumulation, so far, appears to remain, well, offshore. How long these dynamics dominate only time will tell…….

  48. eyesonu says:

    Looks like this baby will bring a good bit of rain to the eastern half of the eastern states over the next few days.

    Can we order her twin sister for the same song and dance in mid to late July?

  49. Mick May says:

    I’m sorry this off topic here but……This morning it was predicted by the Met. Office that it would be sunny and the hottest day of the year here in (west) London…..since mid-morning it has rained on and off all the way through to late afternoon….I suppose that’s the best you can do when you buy a multi-million pound ‘laptop’ computer! ….(sarc)
