554 ABNT20 KNHC 301735 TWOAT Tropical Weather Outlook NWS National Hurricane Center Miami FL 200 PM EDT Wed Jun 30 2021 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: Showers and thunderstorms associated with a broad low pressure area and tropical wave located about 1300 miles east-southeast of the Windward Islands have become better organized since yesterday. However, recent satellite wind data indicates that the disturbance does not have a well-defined circulation. Environmental conditions appear generally favorable for continued development, and a tropical depression or storm is likely to form during the next day or two while the system moves west-northwestward at 20 to 25 mph. Interests in the Lesser Antilles should closely monitor the progress of this system, as advisories on a potential tropical cyclone, accompanied by tropical storm watches for portions of this area, are likely to be issued later today. * Formation chance through 48 hours...high...70 percent. * Formation chance through 5 days...high...90 percent. Showers and thunderstorms continue in association with a tropical wave located over the Lesser Antilles. This system has become less organized since yesterday, and significant development is no longer expected while it moves quickly westward across the Caribbean Sea. The wave should continue to produce locally heavy rains over portions of the Lesser Antilles through tonight. * Formation chance through 48 hours...low...near 0 percent. * Formation chance through 5 days...low...near 0 percent. $$ Forecaster Beven
TRACKING THE TROPICS UPDATE:"
STILL MONITORING TWO TROPICAL WAVES WHICH ARE BOTH STORM INVESTIGATIONS.
1. INVEST 95L: WHICH HAS A FORMATION LOW CHANCE THROUGH 48HS 10% AND LOW 10% THROUGH 5-DAYS. MODELS SHOW THIS SYSTEM WEAKENING QUICKLY AND DISSIPATING.
2. INVEST 97L: WHICH SEEMS TO BE THE HEALTHIEST OF THE TWO WAVES AND GFS MODEL TENDS TO TRACK THIS ONE FURTHER ACROSS THE CARIBBEAN AND INTO THE SOUTHEAST GULF OF MEXICO AS A TROPICAL CYCLONE. THIS WAVE TO ME IS THE ONE TO MONITOR CLOSELY FOR NOW.
97L HAS A HIGH FORMATION CHANCE 80% THROUGH 5-DAYS.
PLEASE NOTE THAT THE GFS IS A LONG RANGE FORECAST MODEL AND THERE IS ALWAYS ERROR IN THE FORECAST RUN. HOWEVER, PERSISTENCE IN THE MODEL RUN WILL ALWAYS GRAB MY ATTENTION.
THE EUROPEAN MODEL DOES NOT SHOE MUCH BUT THAT COULD CHANGE IN TIME.

000 ABNT20 KNHC 301138 TWOAT Tropical Weather Outlook NWS National Hurricane Center Miami FL 800 AM EDT Wed Jun 30 2021 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: A broad area of low pressure, associated with a tropical wave, is located about midway between the west coast of Africa and the Windward Islands. This system is producing a large area of showers and thunderstorms that continues to show some signs of organization. Environmental conditions appear generally favorable for development, and a tropical depression is likely to form during the next few days while the system moves west-northwestward at about 20 mph. Interests in the Windward and Leeward Islands should closely monitor this system as it will likely be moving through that region on Friday. * Formation chance through 48 hours...medium...60 percent. * Formation chance through 5 days...high...80 percent. Disorganized showers and thunderstorms continue in association with a tropical wave located just east of the Lesser Antilles. Significant development of this system is unlikely while it moves quickly westward to west-northwestward at 20 to 25 mph, passing through the Lesser Antilles today and then across the eastern and central Caribbean Sea later this week. Regardless of development, this system could bring locally heavy rainfall to portions of the Lesser Antilles during the next day or two. * Formation chance through 48 hours...low...10 percent. * Formation chance through 5 days...low...10 percent. $$ Forecaster Beven
