TROPICAL SATELLITE ANALYSIS OF THE Atlantic Ocean image shows at 2100 Z SEPT 20 2014 the following -----------------------Developing Tropical Cyclones--------------------------------- INVEST 95 L 15.03 N 21.02 W Showers and thunderstorms have become more concentrated in association with an elongated area of low pressure located a couple hundred miles east-southeast of the Cape Verde Islands. However, development of this system is becoming less likely due to increasingly unfavorable upper-level winds. This low should move generally northwestward and could bring heavy rainfall to portions of the Cape Verde Islands later this weekend. * Formation chance through 48 hours...low...10 percent. * Formation chance through 5 days...low...10 percent. ----------TWO North Atlantic (non tropical) Low Pressure Storm----------- One North Atlantic Low Pressure System That Is Located At 29.00 N 77.00 W ----------------------------ONE Tropical Waves------------------------------------ One Tropical wave that is located at 16.00 N 51.00 W to 11.00 N 56.00 W ----------------------Rements Of Post Tropical Cyclone-------------------------- Renments Of Post Cyclone Edouard that was at 38.00 N 35.00 W --------------------------------GULF OF MEXICO------------------------------------ THE SOUTHERNMOST POINT OF AN ATLANTIC OCEAN COLD FRONT REACHES 32N58W.
