000 ABNT20 KNHC 292324 TWOAT 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. $$ Forecaster Beven

STORM INVEST 99L 1100 PM EDT 9/29/17
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.

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.

BRYAN NORCROSS UPDATE ON MARIA AND CARIBBEAN DISTURBANCE
Bryan Norcross added 2 new photos.
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.

SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Tropical Storm Warning is in effect for... * Cape Hatteras to the North Carolina/Virginia border * Albemarle and Pamlico Sounds These warnings will likely be discontinued this evening. For storm information specific to your area, including possible inland watches and warnings, please monitor products issued by your local National Weather Service forecast office. DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 500 PM EDT (2100 UTC), the center of Hurricane Maria was located near latitude 36.2 North, longitude 72.1 West. Maria is moving toward the north-northeast near 7 mph (11 km/h), and this motion is expected to continue tonight. Maria is forecast to accelerate east-northeastward on Thursday through Friday. On the forecast track, Maria will move away from the coast of North Carolina through Thursday. Maximum sustained winds are near 75 mph (120 km/h) with higher gusts. Some gradual weakening is forecast during the next 48 hours. Hurricane-force winds extend outward up to 105 miles (165 km) primarily to the northeast of the center, and tropical-storm-force winds extend outward up to 230 miles (370 km). The estimated minimum central pressure is 979 mb (28.91 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Tropical storm conditions are expected within the warning area through the next few hours. These winds should diminish later this evening. STORM SURGE: Water levels along the North Carolina Outer Banks will gradually subside tonight. SURF: 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.

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.
