    RECAP "Hurricane Dorian: A True Tropical Beast"

    ** There are no immediate tropical threats to Jacksonville/NE Fl. & SE Ga. or any of the coastal U.S. anytime soon. An offshore storm over the NW Atlantic will produce gusty winds, beach erosion & some heavy coastal rain for New England into Friday **

    ..... & we'll need to watch the Caribbean &/or Gulf of Mexico the next few weeks for the possibility of attempts at tropical development.

    Cat. 5 hurricane Michael devastated the Central Fl. Panhandle one year ago - on Oct. 10th.  Read my blog about the storm * here *.... my visit to Ground Zero * here *... a podcast of victim's memories in their own words * here *.

    Right now: An area of low pressure is taking shape over the Northwest Atlantic southeast of New England. This low will remain just about stationary or meander - possibly even loop -  through Friday until the low is picked up by trough moving into the Northeast U.S. Some subtropical (hybrid) development is possible with this low, but the system will eventually move northeast away from the U.S. over the weekend.  Still... there will be rough seas & surf for parts of the Mid Atlantic & New England along with gusty winds & heavy rain close to the coast.

    This ocean storm will have no impact on Jacksonville/NE Fl./SE Ga.

     

     

    An examination of dust over the Atlantic shows generally less dust over the basin vs. past months. Much too much is made of the dust & tropical cyclones.  It's not all uncommon for tropical waves to simply "wait out" the dry air & dust organizing once the wave is clear of the dry atmosphere.

    2019 names..... "Melissa" is next on the Atlantic list (names are picked at random... repeat every 6 years... historic storms are retired (Florence & Michael last year) & Dorian is almost certain to be next:

     

    East Atlantic:

    Thunderstorms have been rather persistent over the SW Caribbean.  Some development is possible, but the disturbance will then move into Central America over land fairly soon.

    Mid & upper level wind shear (enemy of tropical cyclones) analysis (CIMMS). The red lines indicate strong shear of which there is plenty across the Atlantic at the moment:

    The Atlantic Basin:

    Water vapor imagery (dark blue indicates dry air):

    Deep oceanic heat content is extreme over the NW Caribbean:

    Sea surface temp. anomalies show a warm Gulf of Mexico, Central & Northwest Atlantic while the "Main Development Region" (MDR) remain cooler than avg.  A pocket of cool water temps. has expanded over the SW Atlantic including the Bahamas:

    While parts of the Atlantic are cooler than avg., it's important to realize the water is still warm enough to support tropical systems....

    Global tropical activity:

    Super typhoon "Hagibis" is forecast to hit Japan by the weekend with major impacts on Tokyo - local info. * here *.  Not as strong as the storm currently is but still significant with sustained winds at Cat. 1 hurricane force - 80-90 mph....
