By the middle of next week, strong upper-level winds are likely to limit additional development as the system turns northward and moves closer to the southeastern coast of the United States. * Formation chance through 48 hours...low...20 percent. * Formation chance through 5 days...medium...40 percent. A non-tropical low pressure system is located about 1000 miles west-southwest of the Azores. Conditions are expected to become conducive for this low to acquire subtropical or tropical characteristics during the next day or so, and a subtropical or tropical cyclone is likely to form by early next week while the low meanders over the central Atlantic Ocean. Additional information on this system can be found in High Seas Forecasts issued by the National Weather Service. * Formation chance through 48 hours...medium...60 percent. * Formation chance through 5 days...high...70 percent. && Public Advisories on Kirk are issued under WMO header WTNT32 KNHC and under AWIPS header MIATCPAT2.

113 ABNT20 KNHC 221111 TWOAT Tropical Weather Outlook NWS National Hurricane Center Miami FL 800 AM EDT Sat Sep 22 2018 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: The National Hurricane Center is issuing advisories on Tropical Depression Eleven, located about 500 miles east of the Windward Islands. Shower and thunderstorm activity continues to become better organized near the center of a low pressure system located about 500 miles south of the southern Cabo Verde Islands, and a tropical depression appears to be forming. If these trends continue, advisories will be initiated on this system later today while the low moves westward at about 20 mph. * Formation chance through 48 hours...high...80 percent. * Formation chance through 5 days...high...80 percent. A broad area of low pressure located about 200 miles south of Bermuda is producing only minimal shower activity. Strong upper- level winds are expected to diminish by Sunday or Monday, which could allow for some slow development of this system while it moves westward and then northwestward over the southwestern Atlantic Ocean. By the middle of next week, upper-level winds are likely to strengthen again, which would limit additional development as the system moves closer to the southeastern coast of the United States. * Formation chance through 48 hours...low...10 percent. * Formation chance through 5 days...low...30 percent. Satellite imagery indicates that a non-tropical low pressure system is forming along a frontal boundary about 900 miles west-southwest of the Azores. Conditions are expected to become conducive for the low to acquire subtropical or tropical characteristics, and a subtropical or tropical cyclone is likely to form by early next week while the low meanders over the central Atlantic Ocean.
