Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 PM EDT Fri Sep 29 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 Atlantic Ocean several hundred
miles southeast of Halifax, Nova Scotia, and on Tropical Storm Lee,
located over the north Atlantic Ocean about 1000 miles
west-northwest of the Azores.

A weak low pressure area over the southern Florida Peninsula is
interacting with an upper-level low to produce a large but
disorganized area of cloudiness and showers extending from the
northwestern Caribbean Sea northward through the Florida peninsula.
Environmental conditions appear to be marginally conducive for some
additional development before the upper-level winds become
unfavorable early next week.  Regardless of development, this system
is likely to produce locally heavy rainfall over portions of western
Cuba, the Florida Keys, and the Florida peninsula during the next
several days while the system moves northwestward to northward.
* Formation chance through 48 hours...medium...40 percent.
* Formation chance through 5 days...medium...40 percent.

A tropical wave is producing cloudiness and showers over the
northeastern Caribbean Sea and the adjacent Atlantic waters.
There are no signs of organization and upper-level winds are not
currently conducive for development.  However, conditions could
become a little more favorable for some development next week while
the wave moves toward the west-northwest.  This system is expected
to bring locally heavy rains over the northern Leeward Islands,
including Puerto Rico and the U.S. Virgin Islands.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...low...20 percent.

MONITORING TWO AREA IN THE TROPICS 1212 PM EDT 9/29/17

1. I am still monitoring Storm Investigation 99L off the Southwest Florida Coast .  Some development is possible as it track along the coast but so far so far it does look like it will be a strong system.  looking at a depression may be a tropical storm at this time.  Let's not drop our guard thou since things could change.

2.  Also monitoring a strong wave east of the Lesser Antilles that is interacting with an upper level low southwest of Puerto Rico.  This system is forecast to track northwest over Puerto Rico and bring unwanted heavy rains to the island.  This system will also be monitored for tropical cyclone formation.  It has a 0% chance within the next 48 hrs and a 20% chance within 5 days.

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 AM EDT Fri Sep 29 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 south of Halifax, Nova Scotia, and on Hurricane Lee, located
over the north Atlantic Ocean several hundred miles south-southeast
of Newfoundland.

A broad trough of low pressure interacting with an upper-level
low is producing a large but disorganized area of cloudiness and
showers. This activity extends from the northwestern Caribbean
Sea northward across western Cuba to the southern Florida peninsula.
This trough has moved slowly westward since yesterday, and a weak
low is now likely to form from this system near the west coast of
Florida during the weekend.  Environmental conditions appear to be
conducive for some development of the low before the upper-level
winds become less favorable early next week. 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 during the next several days.
* Formation chance through 48 hours...medium...40 percent.
* Formation chance through 5 days...medium...40 percent.

A tropical wave is producing cloudiness and showers over the
northeastern Caribbean Sea and the adjacent Atlantic waters.
Although there are no signs of organization and surface pressures
are not falling at this time, conditions could become a little more
favorable for some development next week while the system moves
toward the west-northwest.  This system is expected to bring
locally heavy rains over the northern Leeward Islands, including
Puerto Rico and the U.S. Virgin Islands.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...low...20 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

Bryan Norcross added 2 new photos.

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.

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
