Hurricane Summary POSTED: July 31, 2014 5:47 p.m. Low East of the Lesser Antilles Has Gale Force Winds But Lacks Organization So Far A U.S. Air Force reconnaissance C130 aircraft investigated a low pressure area about 400 miles east of the Lesser Antilles Thursday afternoon. This system is moving west northwest at 15-20 mph. Data from the aircraft found few strong wind areas north and northeast of the storm center with estimated surface winds of 40-45 mph. But these winds were found well north and northeast of the low level center. So, the wind field looks more like a hybrid storm than a pure tropical one probably due to the dry stable air affecting the northern periphery. Wind data gathered by the hurricane hunter aircraft did show a nice counter clockwise spiral typical of a developing tropical system. However, drier air to the north of the system is keeping thunderstorm development in the northern simi-circle suppressed. All thunderstorms and stronger convection is south and southwest of the low pressure center due to a combination of dry stable air and some northerly shear. The system could still be classified as a depression or weak tropical storm based on just the wind criteria. But the overall presentation of the system looks pretty lame. The system has about another 12 to 18 hours of lower shear in order to develop. If it takes advantage of this diminished shear and if the dry air becomes less hostile the system could become more of a true tropical storm. The low will track into the northern Windward Islands tomorrow evening then pass over or near Puerto Rico by late Saturday. This will bring gusty winds and showery rainfall over the northern Windward Islands and The Leeward Islands tomorrow night and into the Virgin Islands and Puerto Rico Saturday. The low will track over or just east of the Turks and Caicos Islands during Sunday and near the eastern Bahamas Monday. The more reliable computer forecasts show the system remaining weak as it moves northeast of the Bahamas by Tuesday. The rest of the Atlantic Basin remains relatively quiet By AccuWeather Senior Meteorologist Dan Kottlowski
