ZCZC MIATWOAT ALL TTAA00 KNHC DDHHMM Tropical Weather Outlook NWS National Hurricane Center Miami FL Issued by the NWS Weather Prediction Center College Park MD 200 PM EDT Tue Jun 15 2021 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: The National Hurricane Center is issuing advisories on Tropical Storm Bill, located a few hundred miles south-southeast of Halifax, Canada. 1. Disorganized showers and thunderstorms continue over the Bay of Campeche and southern Mexico in association with a broad low pressure area. This system is expected to move little during the next day or two, and any development should be slow to occur during that time period due to its close proximity to land. However, the disturbance should begin to move northward by Thursday, and a tropical depression is likely to form late in the week when the low moves across the central and northwestern Gulf of Mexico. Regardless of development, heavy rainfall will continue over portions of Central America and southern Mexico during the next several days. Heavy rains could also begin to impact portions of the northern Gulf Coast on Friday. Please consult products from your local meteorological service for more information. * Formation chance through 48 hours...medium...40 percent. * Formation chance through 5 days...high...80 percent. 2. Shower activity is limited in association with a tropical wave located a few hundred miles south-southwest of the Cabo Verde Islands. Development, if any, should be slow to occur during the next couple of days while the wave moves westward. Thereafter, a combination of dry air aloft and strong upper-level winds should end the chances of formation when the wave reaches the central tropical Atlantic. * Formation chance through 48 hours...low...10 percent. * Formation chance through 5 days...low...10 percent.
