Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 PM EDT Thu Sep 28 2017

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

The National Hurricane Center is issuing advisories on Tropical
Storm Maria, located over the western Atlantic Ocean a few hundred
miles west-northwest of Bermuda, and on Hurricane Lee, located over
the central Atlantic Ocean several hundred miles east-northeast of
Bermuda.

A large area of cloudiness and showers extending from the
northwestern Caribbean Sea northward across Cuba to the Florida
Straits is associated with a broad surface trough interacting with
an upper-level low.  A weak area of low pressure is likely to form
from this weather system near the Florida Straits on Friday, and it
is forecast to move northward near the east coast of the Florida
Peninsula through Saturday.  Environmental conditions appear
to be conducive for some development during the next couple of days,
before upper-level winds become less favorable on Sunday.
Regardless of development, this system is likely to produce
locally heavy rainfall over portions of central and western Cuba,
the Florida Keys, the Florida peninsula, and the northwestern
Bahamas during the next several days.
* Formation chance through 48 hours...medium...40 percent.
* Formation chance through 5 days...medium...50 percent.

MONITORING INVEST 99L NORTH OF THE CUBAN COAST

 STORM INVESTIGATION 99L

A TROUGH OF LOW PRESSURE NORTH OF THE CUBAN COAST THAT MOVED NORTH FROM THE CARIBBEAN HAS SOME POTENTIAL FOR A TROPICAL DEPRESSION OR TROPICAL STORM TO DEVELOP DURING THE NEXT COUPLE OF DAYS. 

AS THIS SYSTEM BEGINS TO DEVELOP IT WILL DRAW UP MOISTURE FROM THE TROPICS OVER CUBA AND THE FLORIDA PENINSULA AND SOME OF THESE RAINS COULD PRODUCE A FLOOD PROBLEM FOR THE STATE AS IT TRACKS SLOWLY NORTHWARD.  STAY TUNED TO LOCAL MEDIA FOR UPDATES  ON THIS SYSTEM.


ELSEWHERE WE HAVE MARIA FINALLY LEAVING AND LEE REMAINS A NO THREAT TO LAND HURRICANE.

WE WILL HAVE TO MONITOR CLOSELY THE CARIBBEAN AND GULF OF MEXICO IN OCTOBER FOR UNWELCOME TROPICAL CYCLONE FORMATION.

TROPICAL WEATHER OUTLOOK 1216 PM EDT 09/28/17

STILL MONITORING THE CARIBBEAN FOR WEAK DEVELOPMENT ALONG THE FLORIDA COAST.  I SAY WEAK DEVELOPMENT BUT IT COULD BE A GUSTY AND WET DISTURBANCE THAT COULD PRODUCE HEAVY RAINFALL OVER A PORTION OF FLORIDA.

BRYAN NORCROSS UPDATE ON MARIA AND CARIBBEAN DISTURBANCE

Thursday update on TROPICAL STORM MARIA and FUTURE TROPICS: Maria is moving away from the U.S. East Coast. The high winds have already moved offshore, but the ocean will remain agitated and dangerous as strong swells continue to impact the coast. The elevated water levels around the Outer Banks will slowly decrease, but some minor sound-side flooding could still occur today at high tide. Maria is forecast to be a memory by the end of the weekend.
Cooler air will move in as Maria moves out, though it’s not the end of the oddly warm fall in the East. Another round of unusually warm weather is coming.

Over the weekend, we’ll keep an eye on the waters around Florida. A cold front moving south may meet up with a weak disturbance in the tropics to form a low-pressure system with some tropical-development potential. The odds are not high that a significant storm would form, but it’s not impossible that we get a rainy, gusty disturbance.

In the long range, another unusually strong and hot high-pressure system is forecast to cover a good part of the Midwest, East, and Southeast. If the forecast is right, on the south side of the heat bubble, a noticeably strong, persistent east wind will set up over Florida, and south of that the atmospheric pattern could be favorable for tropical development. That would be at the end of next week.
Stay tuned. Hurricane season isn’t over yet.

EYES OF THE CARIBBEAN DISTURABANCE INTO NEXT WEEK

Quick review of the new Storm Invest in the Caribbean I been mentioning for the past week of so. Although some models do not suggest strong development and more like a rain event, we need to monitor this area closely seeing how this season has been thus far.

The sea surface temps in this region are 30-31°C or 86-88°F. Perfect fuel for tropical cyclone to develop and strengthen in.

We don't want any surprises and want to be ready specially those in the Florida straits that suffered the most from Irma. Remember this is a closer system to home and if it did develop and strengthen unexpectedly it would not give folks in the Florida straits ample time to get out. Luckily we have a large land mass between this system and Florida.

Upper level winds are forecast to become unfavorable north of the Grand Bahamas as this system tracks north-northwest toward the east of Florida maybe that will not give it much time to develop.

I am not trying to hype things up, its just this season, I have learned not to trust, any of these so called weak developing system. Good example of that is baby major Hurricane Lee in the Atlantic. That system was written off then it made a come back and reached major storm status this morning. So please stay tuned to local news via TV or local radio and I will do my best to keep you up to date in the coming days.

A Storm Surge Warning means there is a danger of life-threatening
inundation, from rising water moving inland from the coastline in
the indicated locations. For a depiction of areas at risk, please
see the National Weather Service Storm Surge Watch/Warning Graphic,
available at hurricanes.gov.  This is a life-threatening situation.
Persons located within these areas should take all necessary actions
to protect life and property from rising water and the potential for
other dangerous conditions.  Promptly follow evacuation and other
instructions from local officials.

A Tropical Storm Warning means that tropical storm conditions are
expected somewhere within the warning area.

A Storm Surge Watch means there is a possibility of life-
threatening inundation, from rising water moving inland from the
coastline in the indicated locations. For a depiction of areas at
risk, please see the National Weather Service Storm Surge
Watch/Warning Graphic, available at hurricanes.gov.

For storm information specific to your area, including possible

DISCUSSION AND 48-HOUR OUTLOOK
------------------------------
At 1100 AM EDT (1500 UTC), the center of Hurricane Maria was located
near latitude 35.6 North, longitude 72.6 West. Maria is moving
toward the north-northeast near 6 mph (9 km/h), and this motion is
expected to continue today. Maria is forecast to accelerate
east-northeastward on Thursday and Thursday night. On the forecast
track, Maria will begin to move away from the coast of North
Carolina later today and tonight.

Reports from an Air Force Reserve reconnaissance aircraft indicate
that the maximum sustained winds are near 75 mph (120 km/h) with
higher gusts.  Some weakening is forecast during the next 48 hours.

Hurricane-force winds extend outward up to 105 miles (165 km)
primary to the northeast of the center, and tropical-storm-force
winds extend outward up to 230 miles (370 km). An observing site at
Jennette's Pier in Nags Head, North Carolina, recently reported a
sustained wind of 43 mph (69 km/h) and a gust of 51 mph (81 km/h).

The estimated minimum central pressure based on reconnaissance
aircraft data is 978 mb (28.88 inches).


HAZARDS AFFECTING LAND
----------------------
WIND:  Tropical storm conditions are expected within the warning
area through today.

STORM SURGE:  The combination of a dangerous storm surge and the
tide will cause normally dry areas near the coast to be flooded by
rising waters moving inland from the shoreline.  The water is
expected to reach the following heights above ground if the peak
surge occurs at the time of high tide...

Ocracoke Inlet to Duck including the sound side of the Outer
Banks...2 to 4 ft

Surge-related flooding depends on the relative timing of the surge
and the tidal cycle, and can vary greatly over short distances.  For
information specific to your area, please see products issued by
your local National Weather Service forecast office.

SURF:  Large swells generated by Maria are affecting much of the
east coast of the United States, Atlantic Canada, Bermuda, the
Bahamas, and the Turks and Caicos Islands.  These swells are likely
to cause life-threatening surf and rip current conditions.  Please
consult products from your local weather office for more
information.
