TTAA00 KNHC DDHHMM Tropical Weather Outlook NWS National Hurricane Center Miami FL 800 AM EDT Sun Aug 20 2017 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: 1. Showers and thunderstorms have increased this morning in association with the remnants of Harvey. Gradual development of this system is possible, and it could become a tropical cyclone once again as it moves west-northwestward across the central and northwestern Caribbean Sea during the next couple of days. Interests in northern Nicaragua, Honduras, Belize, and the Yucatan peninsula should monitor the progress of this system. An Air Force Reserve reconnaissance aircraft is scheduled to investigate this disturbance later today. * Formation chance through 48 hours...medium...50 percent * Formation chance through 5 days...medium...60 percent 2. A trough of low pressure located a couple of hundred miles north of Puerto Rico continues to produce disorganized showers and thunderstorms. Environmental conditions are expected to be unfavorable for development of this system during the next couple of days, but they could become slightly more conducive for development by midweek when the system is near the northwestern Bahamas or Florida. * Formation chance through 48 hours...low...10 percent. * Formation chance through 5 days...low...20 percent. 3. A large area of cloudiness and disorganized thunderstorms located about 1000 miles east of the northern Leeward Islands is associated with a trough of low pressure. This system is currently embedded in a dry air mass, and upper-level winds are expected to become too strong to support development in a day or so. Therefore, tropical cyclone formation is not likely while this system moves northwestward at about 15 mph. * Formation chance through 48 hours...low...10 percent. * Formation chance through 5 days...low...10 percent.

TTAA00 KNHC DDHHMM Special Tropical Weather Outlook NWS National Hurricane Center Miami FL 420 PM EDT Sun Aug 20 2017 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: Special Tropical Weather Outlook issued to update discussion on the remnants of Harvey. 1. Updated: An Air Force Reserve Unit Hurricane Hunter aircraft investigating the remnants of Harvey found that the system still lacks a well-defined center of circulation, and so far there is no indication of winds to tropical storm force. Satellite images indicate that the associated showers and thunderstorms have changed little in organization since earlier today. Gradual development of this system is possible, and it could become a tropical cyclone once again while it moves west-northwestward across the northwestern Caribbean Sea, near the northern coast of Honduras, during the next day or two. The system is expected to reach Belize or the Yucatan Peninsula on Tuesday, and then move into the Bay of Campeche by the middle of the week, where redevelopment appears more likely. Interests in northern Nicaragua, Honduras, Belize, and the Yucatan Peninsula should monitor the progress of this system. * Formation chance through 48 hours...medium...50 percent. * Formation chance through 5 days...high...70 percent. |

TTAA00 KNHC DDHHMM Tropical Weather Outlook NWS National Hurricane Center Miami FL 800 PM EDT Sun Aug 20 2017 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: 1. Data from an Air Force Reserve Hurricane Hunter mission earlier this afternoon indicated that the remnants of Harvey, located over the central Caribbean Sea, do not have a well-defined center of circulation. In addition, the associated shower and thunderstorm activity remains disorganized and has decreased in coverage and intensity since earlier in the day. Gradual development of this system is still possible through Monday night while it moves west-northwestward at 15 to 20 mph near the coast of Honduras, and it could become a tropical cyclone again before it reaches the coast of Belize or the Yucatan Peninsula early Tuesday. The remnants are expected to move into the Bay of Campeche on Wednesday, where redevelopment appears more likely due to more favorable upper-level winds. Interests in northern Nicaragua, Honduras, Belize, and the Yucatan Peninsula should monitor the progress of this system. * Formation chance through 48 hours...medium...50 percent. * Formation chance through 5 days...high...80 percent. 2. A trough of low pressure located about a hundred miles north-northeast of the Turks and Caicos Islands is producing an elongated area of disorganized showers and thunderstorms that extends southeastward toward Puerto Rico and the Virgin Islands. Environmental conditions are expected to be unfavorable for development of this system during the next couple of days while it moves west-northwestward at about 15 mph toward the northern Bahamas and southern Florida. Conditions could become a little more conducive for development later in the week when the system is near Florida or the adjacent waters of the western Atlantic or eastern Gulf of Mexico. * Formation chance through 48 hours...low...10 percent. * Formation chance through 5 days...medium...40 percent. 3. A large area of cloudiness and disorganized thunderstorms located about 900 miles east-northeast of the northern Leeward Islands is associated with a trough of low pressure. Upper-level winds are not conducive for development of this system while it moves northwestward over the central Atlantic at 10 to 15 mph. * Formation chance through 48 hours...low...near 0 percent. * Formation chance through 5 days...low...near 0 percent.

TTAA00 KNHC DDHHMM Tropical Weather Outlook NWS National Hurricane Center Miami FL 800 AM EDT Mon Aug 21 2017 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: 1. A trough of low pressure, associated with the remnants of Harvey, continues to produce a large area of disorganized showers and thunderstorms over the northwestern Caribbean Sea. Some development of this system is still possible before it reaches the coast of Belize or the Yucatan Peninsula early Tuesday. The disturbance is forecast to move into the Bay of Campeche early Wednesday, where environmental conditions are expected to be more conducive for redevelopment. Regardless of development, locally heavy rainfall and gusty winds are likely to spread westward across northern Nicaragua, Honduras, Belize, and the Yucatan Peninsula during the next couple of days. The Air Force reconnaissance aircraft mission scheduled for today has been canceled. * Formation chance through 48 hours...medium...50 percent. * Formation chance through 5 days...high...80 percent.

TTAA00 KNHC DDHHMM Tropical Weather Outlook NWS National Hurricane Center Miami FL 800 PM EDT Mon Aug 21 2017 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: 1. A large area of disturbed weather over the northwestern Caribbean Sea is associated with the remnants of Harvey. Satellite images and surface observations indicate that the system lacks a well-defined circulation and surface pressures are not falling at this time. Although this system could still become better organized while approaching the Yucatan peninsula tonight and early Tuesday, tropical cyclone formation is not expected until the disturbance moves into the Bay of Campeche on Wednesday where conditions are favorable. Regardless of development, locally heavy rainfall and gusty winds are likely to spread westward primarily across Belize and the Yucatan Peninsula during the next couple of days. * Formation chance through 48 hours...high...70 percent. * Formation chance through 5 days...high...90 percent. 2. A broad trough of low pressure located near the central Bahamas and the adjacent Atlantic continues to produce disorganized showers and thunderstorms. Only slow development of this system is anticipated during the next several days while it moves west-northwestward across the Bahamas and then turns northwestward or northward near Florida and the adjacent waters. * Formation chance through 48 hours...low...20 percent. * Formation chance through 5 days...medium...40 percent.
