000 ABNT20 KNHC 251142 TWOAT Tropical Weather Outlook NWS National Hurricane Center Miami FL 800 AM EDT Sun Aug 25 2019 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: The National Hurricane Center is issuing advisories on Tropical Storm Dorian, located several hundred miles east-southeast of the Lesser Antilles. Showers and thunderstorms remain disorganized in association with a trough of low pressure that extends from the southern Florida peninsula northeastward over the western Atlantic for a few hundred miles. Environmental conditions appear conducive for gradual development, and a tropical or subtropical depression is likely to form within the next few days while the system moves slowly northeastward well offshore of the southeastern United States. Interests along the coasts of South and North Carolina should continue to monitor the progress of this system. An Air Force Reserve Hurricane Hunter aircraft is scheduled to investigate the disturbance this afternoon, if necessary. * Formation chance through 48 hours...medium...60 percent. * Formation chance through 5 days...high...80 percent. && Public Advisories on Dorian are issued under WMO header WTNT35 KNHC and under AWIPS header MIATCPAT5.

The Government of St. Lucia has issued a Tropical Storm Watch for St. Lucia. SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Tropical Storm Warning is in effect for... * Barbados A Tropical Storm Watch is in effect for... * St. Lucia * St. Vincent and the Grenadines A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area within 36 hours. A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, generally within 48 hours. Additional watches could be issued later today for portions of the Windward and Leeward Islands. Elsewhere, interests in Puerto Rico, the Virgin Islands, and Hispaniola should monitor the progress of Dorian. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 1100 AM AST (1500 UTC), the center of Tropical Storm Dorian was located near latitude 11.2 North, longitude 52.9 West. Dorian is moving toward the west near 14 mph (22 km/h), and this motion should continue through tonight. A turn toward the west-northwest is expected on Monday, with this motion continuing through Tuesday night. On the forecast track, the center of Dorian is expected to be near the Windward Islands late Monday or early Tuesday and move into the eastern Caribbean Sea on Tuesday. Maximum sustained winds are near 40 mph (65 km/h) with higher gusts. Some strengthening is forecast during the next 48 hours, and Dorian could be near hurricane strength by Tuesday over the eastern Caribbean Sea. Tropical-storm-force winds extend outward up to 25 miles (35 km) from the center. The estimated minimum central pressure is 1008 mb (29.77 inches). HAZARDS AFFECTING LAND ---------------------- RAINFALL: Dorian is expected to produce total rain accumulations of 2 to 4 inches in portions of the Lesser Antilles, with possible isolated maximum amounts of 6 inches. WIND: Tropical storm conditions are likely in the warning are by late Monday. Tropical storm conditions are possible within the watch area by Monday night or Tuesday. SURF: Swells generated by Dorian will be affecting portions of the Lesser Antilles by late Monday. These swells could cause life- threatening surf and rip current conditions. Please consult products from your local weather office. NEXT ADVISORY ------------- Next intermediate advisory at 200 PM AST. Next complete advisory at 500 PM AST. $$ Forecaster Beven ]]> -

Tropical Storm Dorian Forecast Discussion Number 5
Issued at 1100 AM AST Sun Aug 25 2019 000 WTNT45 KNHC 251449 TCDAT5 Tropical Storm Dorian Discussion Number 5 NWS National Hurricane Center Miami FL AL052019 1100 AM AST Sun Aug 25 2019 The convective organization of Dorian has improved a little since the last advisory, as a more persistent area of central convection has formed along with increased, but ragged, outer banding. However, the various satellite intensity estimates remain clustered around 35 kt, and that remains the initial intensity. A combination of 1-minute GOES-16 visible imagery and microwave satellite data have helped pinpoint the center, and the initial motion is 280/12. The subtropical ridge to the north of the cyclone should steer it generally westward to west-northwestward for the next 3-4 days, with a more northwestward motion possible thereafter as Dorian approaches an upper-level low pressure area forecast to be over the north-central Caribbean. The model guidance continues the previous trend of being south of and a bit faster than the previous runs, and as a result the new forecast track is again shifted a little to the south. The new forecast lies between the previous forecast and the various consensus models. However, it is south of the forecasts of the HWRF, the UKMET, and the UKMET Ensemble mean. Additional adjustments to the track may be required on the next advisory if the current model trends continue. While vertical wind shear is decreasing over Dorian, the cyclone still appears to be ingesting dry air based on the ragged convective pattern. Some dry air entrainment is expected to continue for the next few days, and based on this the new intensity forecast again calls for gradual strengthening through 72 h. This part of the intensity forecast is in best agreement with the SHIPS model, and it lies near the upper edge of the intensity guidance. The intensity forecast becomes low confidence after 72 h due to uncertainties in the amount of shear and land that Dorian will encounter. The new forecast calls for some weakening due to shear before Dorian moves over Hispaniola, followed by weakening to a depression due to passage over the island. However, the large range of possibilities includes both Dorian going north of Hispaniola and remaining a hurricane and the small cyclone dissipating completely over Hispaniola. Key Messages: 1. A Tropical Storm Warning has been issued for Barbados, and a Tropical Storm Watch is in effect for St. Lucia, St. Vincent, and the Grenadines. Additional watches and warnings for other portions of the Lesser Antilles could be required later today. 2. It is too soon to determine the specific timing or magnitude of impacts in Puerto Rico, the Virgin Islands, or Hispaniola, but interests in those areas should monitor the progress of Dorian.

Tropical Depression Ivo Forecast Discussion Number 18
Issued at 800 AM PDT Sun Aug 25 2019 000 WTPZ45 KNHC 251433 TCDEP5 Tropical Depression Ivo Discussion Number 18 NWS National Hurricane Center Miami FL EP102019 800 AM PDT Sun Aug 25 2019 Ivo is moving north-northwestward or 340/10 kt, and that motion is forecast to continue today. A turn to the north with a gradual decrease in forward speed is still expected to occur on Monday, and that motion should continue into Tuesday. The new NHC track forecast is similar to the previous advisory track and lies close a blend of the consensus models HCCA, TVCN, and TVCX. The initial intensity of 25 kt is based on earlier ASCAT surface wind data. Although a small area of deep convection has redeveloped about 100 n mi north of the low-level center, that thunderstorm activity is too far away to provide any positive feedback onto the circulation. Thus, Ivo basically remains devoid of any significant organized convection, and this downward trend is expected to continue for the next 48 hours while the cyclone moves of waters cooler than 22C. As a result of the expected spin down of the shallow vortex, Ivo is forecast to become a post-tropical remnant low later today and dissipate by Tuesday. Although Ivo is weakening, significant swells generated by the cyclone are affecting portions of the west coast of the Baja California peninsula and southern California. These swells are likely to continue through the day and could cause rip currents, and gradually subside on Monday. See products from your local weather office for additional information.
