7AM Update: East Coast Showers, Tracking TS Dorian

  South Florida will see summertime sun and mostly east coast showers and storms on Wednesday, while we all track Tropical Storm Dorian as it moves through the Caribbean.  Here at home, Wednesday features plenty of sun along the Gulf coast, while the rest of us deal with sun, clouds, and periods of showers and storms, especially in the east coast metro area during the afternoon.  Watch out for an increasing risk of dangerous rip currents at the Atlantic beaches.  Highs on Wednesday will be in the low 90s, but it will feel about 10 degrees hotter.

Thursday will flip the precipitation picture, with the western part of South Florida seeing more showers and storms than the east coast metro area.  Thursday’s highs will be in the low to mid 90s, and a heat advisory is possible for some locations.

Friday will feature a mix of sun and clouds with periods of showers and storms.  Friday’s highs will be near 90 degrees.

Look for a mix of sun and clouds with passing showers and storms during the day on Saturday.  Saturday’s highs will be in the upper 80s.

Saturday night through Sunday will all depend on how close Dorian comes to us.  A brush with the system would bring gusty and stormy weather to the east coast metro area and clouds and passing showers and storms to the Gulf coast.  Highs on Sunday will be in the upper 80s.

Tropical Storm Dorian strengthened overnight, and it is affecting the Virgin Islands early on Wednesday.  At 5 am, Dorian was located near 16.8 North, 63.9 West, about 85 miles southeast of St. Croix.  Dorian was moving northwest at 13 miles per hour, and maximum sustained winds were up to 60 miles per hour.  Hurricane watches and tropical storm warnings are up for the U.S. and British Virgin Islands and Puerto Rico, while tropical storm warnings remain for portions of the Dominican Republic.  Heavy rain from Dorian will lead to flash flooding and mudslides in Puerto Rico as the storm passes over or near the island later on Wednesday.  Dorian is then expected to skirt the southeastern Bahamas and move into or near the northwestern Bahamas on Saturday as a hurricane.  The current National Hurricane Center forecast calls for landfall somewhere along the Florida coast on Sunday as a category 2 hurricane.  Most of South Florida remains in the 4-to-5-day “cone” (the Keys and extreme southern Miami-Dade are not as of 5 am Wednesday), so we need to watch Dorian closely for any changes in the track.  We should consider ourselves on stand by and be prepared to take action if necessary.

Elsewhere, Tropical Depression # 6 is now Tropical Storm Erin.   At 5 am Wednesday, Erin was located near 32.5 North, 72.4 West, and was moving northwest at 6 miles per hour.  Maximum sustained winds were 40 miles per hour.  Erin is expected to accelerate as it turns to the northeast on Thursday, all the while losing its tropical characteristics.  It is likely to be at depression strength when it reaches the Canadian Maritimes early on Friday.
