2017-10-27 13:23:49| National Hurricane Center (Atlantic)

000 ABNT20 KNHC 271123 TWOAT Tropical Weather Outlook NWS National Hurricane Center Miami FL 800 AM EDT Fri Oct 27 2017 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: Shower and thunderstorm activity has increased and become more concentrated in association with a trough of low pressure over the northwestern Caribbean Sea. Environmental conditions are expected to be conducive for development today and Saturday, and a tropical depression could form as the system moves northward over the northwestern Caribbean Sea. Increasing upper-level winds will make conditions less favorable when the system moves north of Cuba and merges with a cold front on Sunday. Interests in the Cayman Islands and central and western Cuba should monitor the progress of this system. Regardless of development, this disturbance is expected to produce locally heavy rainfall over the Cayman Islands, Jamaica, and portions of Cuba during the next day or two. These rains are forecast to spread northward across portions of South Florida and the Keys on Saturday, and over the northwestern Bahamas Saturday night and Sunday. An Air Force Reserve reconnaissance aircraft is scheduled to investigate this system this afternoon, if necessary. * Formation chance through 48 hours...medium...60 percent. * Formation chance through 5 days...medium...60 percent. $$ Forecaster Brown
