RECAP "Hurricane Dorian: A True Tropical Beast"
** There are no immediate tropical threats to Jacksonville/NE Fl. & SE Ga. The offshore ocean (subtropical) storm over the NW Atlantic is slowly turning away from New England where conditions will slowly improve **
..... & we'll need to watch the Caribbean &/or Gulf of Mexico through at least the end of the month for the possibility of attempts at tropical development.
Cat. 5 hurricane Michael devastated the Central Fl. Panhandle one year ago 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 *. There will be many local events through the weekend commemorating the storm.
Right now:
Subtropical (not purely tropical or warm core) storm Melissa over the Northwest Atlantic southeast of New England is moving slowly away from New England. The storm will be picked up by a trough moving into the Northeast U.S. over the weekend & taken out to sea. Rain has ended for coastal New England & winds & seas will slowly subside.
Melissa will have no impact on Jacksonville/NE Fl./SE Ga.
Generally unsettled conditions continue over the Caribbean. Low pressure may form within the upcoming week near Central America then move into the SW or Western Gulf of Mexico where some attempts at tropical development will be possible.
Atlantic dust (note the "doughnut" of Melissa in the midst of a large area of dry air/dust):
2019 names..... "Nestor" 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 by early next week.
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:
Typhoon "Hagibis" hit Japan Fri. night into Sat. with major impacts on Tokyo - local info. * here *. The tropical cyclone will be off its peak but still significant with sustained winds potentially at Cat. 1 hurricane force - 75+ mph....
