000 ABNT20 KNHC 191752 TWOAT TROPICAL WEATHER OUTLOOK NWS NATIONAL HURRICANE CENTER MIAMI FL 200 PM EDT WED OCT 19 2016 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: A broad, non-tropical low pressure system is located about 250 miles northeast of the Turks and Caicos Islands. Although shower and thunderstorm activity has decreased and become less organized since yesterday, environmental conditions are forecast to become a little more conducive for the low to acquire some tropical characteristics, and a subtropical or tropical cyclone is likely to form within the next couple of days. The low is forecast to move northwestward tonight and Thursday, then turn north-northeastward on Friday, and merge with a cold front over the western Atlantic by the weekend. A NOAA reconnaissance aircraft is scheduled to investigate this system Thursday afternoon, if necessary. Regardless of development, locally heavy rainfall is possible over Hispaniola, Puerto Rico, and portions of the northern Leeward Islands through tonight. * Formation chance through 48 hours...medium...60 percent * Formation chance through 5 days...high...80 percent $$ Forecaster Stewart
