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
