389 ABNT20 KNHC 211154 TWOAT Tropical Weather Outlook NWS National Hurricane Center Miami FL Issued by the NWS Weather Prediction Center College Park MD 800 AM EDT Fri Sep 21 2018 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: Showers and thunderstorms associated with a tropical wave located about 600 miles southeast of the Cabo Verde Islands are showing some signs of organization. The environment is forecast to be conducive for slow development, and a tropical depression could form early next week while the system moves westward at 15 to 20 mph across the low latitudes of the eastern and central tropical Atlantic Ocean. * Formation chance through 48 hours...low...20 percent. * Formation chance through 5 days...medium...60 percent. A weak low pressure area located about 600 miles east of the Windward Islands is producing disorganized showers and thunderstorms. The combination of dry mid-level air and strong upper-level winds is expected to hinder any further development of this low while it moves west-northwestward at around 10 mph. * Formation chance through 48 hours...low...10 percent. * Formation chance through 5 days...low...10 percent. A broad area of low pressure located just southeast of Bermuda is producing minimal shower activity while it moves southward at 10 to 15 mph. Although a combination of dry air and strong upper-level winds is expected to inhibit any significant development over the next few days, the environment could become conducive for slow development when the system moves over the southwest Atlantic Ocean during the middle part of next week. * Formation chance through 48 hours...low...near 0 percent. * Formation chance through 5 days...low...20 percent. A non-tropical low pressure system is forecast to develop tonight over the central subtropical Atlantic Ocean midway between Bermuda and the Azores. Conditions are expected to be conducive for the low to acquire subtropical or tropical characteristics, and a subtropical or tropical cyclone is expected to form late this weekend or early next week while the low meanders over the central Atlantic Ocean. * Formation chance through 48 hours...low...10 percent. * Formation chance through 5 days...high...70 percent. $$ Forecaster Campbell/Blake

480 ABNT20 KNHC 210515 TWOAT Tropical Weather Outlook NWS National Hurricane Center Miami FL 200 AM EDT Fri Sep 21 2018 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: A tropical wave located more than 700 miles southeast of the Cabo Verde Islands. Some gradual development of this system is possible during the next several days as the disturbance moves westward at 15 to 20 mph across the low latitudes of the eastern and central tropical Atlantic Ocean. * Formation chance through 48 hours...low...10 percent. * Formation chance through 5 days...medium...50 percent. A small but concentrated area of showers and thunderstorms associated with a tropical wave is located about 650 miles east of the Windward Islands. The combination of dry mid-level air and strong upper-level winds is expected to hinder any development of this disturbance while it moves westward to west-northwestward at around 10 mph. * Formation chance through 48 hours...low...10 percent. * Formation chance through 5 days...low...10 percent. A non-tropical area of low pressure located less than 100 miles northeast of Bermuda, is moving southward at 10 to 15 mph. Shower activity has diminished significantly during the past several hours, and the combination of dry air and strong upper-level winds is expected to inhibit any significant development for the next several days while the system moves southward on Friday, and then drifts westward to the southwest of Bermuda over the weekend. * Formation chance through 48 hours...low...10 percent. * Formation chance through 5 days...low...20 percent. Another non-tropical low pressure system is forecast to develop by Friday night over the central subtropical Atlantic Ocean midway between Bermuda and the Azores. Conditions are expected to be conducive for the low to acquire subtropical or tropical characteristics, and a subtropical or tropical cyclone is expected to form late this weekend or early next week while the low meanders over the central Atlantic Ocean. * Formation chance through 48 hours...low...near 0 percent. * Formation chance through 5 days...high...70 percent. $$ Forecaster Stewart

186 ABNT20 KNHC 202344 TWOAT Tropical Weather Outlook NWS National Hurricane Center Miami FL 800 PM EDT Thu Sep 20 2018 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: A small but concentrated area of showers and thunderstorms associated with a tropical wave is located about 650 miles east of the Windward Islands. The combination of dry mid-level air and strong upper-level winds are expected to hinder any development of this disturbance while it moves westward to west-northwestward at 10 to 15 mph. * Formation chance through 48 hours...low...10 percent. * Formation chance through 5 days...low...10 percent. A non-tropical area of low pressure with gale-force winds, located about 100 miles north-northeast of Bermuda, is moving southeastward at about 15 mph. The combination of dry air associated with a weakening frontal system and strong upper-level winds are expected to inhibit any significant development for the next couple of days. However, conditions could become a bit more conducive for this low to gradually acquire some tropical characteristics early next week while the system moves southward on Sunday, and then drifts westward to the southwest of Bermuda on Monday. * Formation chance through 48 hours...low...10 percent. * Formation chance through 5 days...low...20 percent. Another non-tropical low pressure system is forecast to develop by Friday night over the central subtropical Atlantic Ocean midway between Bermuda and the Azores. Conditions are expected to be conducive for the low to acquire some subtropical or tropical characteristics, and a subtropical or tropical cyclone could form late this weekend or early next week while the low meanders over the central Atlantic Ocean. * Formation chance through 48 hours...low...near 0 percent. * Formation chance through 5 days...medium...60 percent. A tropical wave is moving off the coast of Guinea in western Africa. Some slow but gradual development of this system is possible during the next several days as the disturbance moves westward at 15 to 20 mph across the low latitudes of the eastern tropical Atlantic Ocean. * Formation chance through 48 hours...low...10 percent. * Formation chance through 5 days...medium...40 percent. $$ Forecaster Stewart

077 ABNT20 KNHC 201742 TWOAT Tropical Weather Outlook NWS National Hurricane Center Miami FL Issued by the NWS Weather Prediction Center College Park MD 200 PM EDT Thu Sep 20 2018 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: Satellite imagery shows that showers and thunderstorms associated with a westward-moving tropical wave located about 750 miles east of the Windward Islands have become less organized over the last several hours. There is no evidence of a surface circulation at this time, and a combination of dry air and strong upper-level winds are expected to make development of this system unlikely while it moves westward at 10-15 mph. * Formation chance through 48 hours...low...10 percent. * Formation chance through 5 days...low...10 percent. A non-tropical area of low pressure with gale-force winds is located about 150 miles north of Bermuda and is moving south-southeastward at about 15 mph. Although there are some signs of organization, dry air and strong upper-level winds are expected to limit development of this system over the next couple of days. However, conditions could become a bit more conducive for this low to gradually acquire some tropical characteristics early next week as the low moves south and then drifts westward to the southwest of Bermuda. * Formation chance through 48 hours...low...10 percent. * Formation chance through 5 days...low...20 percent. Another non-tropical low pressure system is forecast to develop by Friday night over the central subtropical Atlantic Ocean between Bermuda and the Azores. Conditions are expected to be conducive for the low to acquire some subtropical or tropical characteristics, and a subtropical or tropical cyclone could form late this weekend or early next week while the low meanders over the central Atlantic Ocean. * Formation chance through 48 hours...low...near 0 percent. * Formation chance through 5 days...medium...50 percent. A tropical wave is forecast to emerge off the west coast of Africa by Saturday. Some slow development of this system is possible early next week as it moves quickly westward across the low latitudes of the eastern tropical Atlantic Ocean. * Formation chance through 48 hours...low...near 0 percent. * Formation chance through 5 days...low...20 percent. $$ Forecaster Orrison/Blake
