200 pm edt fri aug 18 2017

for the north atlantic...caribbean sea and the gulf of mexico:

the national hurricane center is issuing advisories on tropical
storm harvey, located just west of the windward islands.

shower and thunderstorm activity associated with an area of low
pressure located about 600 miles east-northeast of the leeward
islands continues to show signs of organization.  however,
upper-level winds are becoming less favorable, and the chances for
a tropical cyclone to form are diminishing.  the low is expected to
move west-northwestward at about 20 mph during the next few days,
and interests in the northern leeward islands should monitor the
progress of this disturbance.
* formation chance through 48 hours...medium...60 percent.
* formation chance through 5 days...medium...60 percent.

a tropical wave is located over the far eastern atlantic ocean
several hundred miles west of the cabo verde islands.  environmental
conditions are forecast to become more favorable for some
development early next week while the system moves
west-northwestward to northwestward at about 20 mph.
* formation chance through 48 hours...low...10 percent.
* formation chance through 5 days...medium...40 percent.

The Government of Barbados has discontinued the Tropical Storm Warning for St. Vincent and the Grenadines, and has discontinued the Tropical Storm Watch for Dominica. The Government of St. Lucia has discontinued the Tropical Storm Warning for St. Lucia. SUMMARY OF WATCHES AND WARNINGS IN EFFECT: There are no coastal watches or warnings in effect. Interests elsewhere in the eastern and central Caribbean Sea should monitor the progress of Harvey. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND 48-HOUR OUTLOOK ------------------------------ At 200 PM AST (1800 UTC), the center of Tropical Storm Harvey was located near latitude 13.2 North, longitude 62.1 West. Harvey is moving toward the west near 21 mph (33 km/h) and this general motion is expected to continue for the next couple of days. On the forecast track, the center of Harvey will move away from the Windward Islands and through the eastern Caribbean Sea this afternoon and tonight. It should then move into the central Caribbean Sea on Saturday. Maximum sustained winds are near 40 mph (65 km/h) with higher gusts. Slow strengthening is forecast during the next 48 hours. Tropical-storm-force winds extend outward up to 70 miles (110 km) mainly to the north of the center. The minimum central pressure estimated from Air Force Reserve Hurricane Hunter aircraft data is 1005 mb (29.68 inches). HAZARDS AFFECTING LAND ---------------------- WIND: Locally gusty winds across the Windward Islands should diminish this afternoon. RAINFALL: Harvey is expected to produce additional rainfall totals of 1 to 2 inches with locally higher amounts across parts of the Leeward and Windward Islands from Guadeloupe southward to Grenada. These additional rains could cause life-threatening flash floods and mudslides. NEXT ADVISORY ------------- Next complete advisory at 500 PM AST. $$ Forecaster Beven ]]>

  • Tropical Storm Harvey Forecast Discussion Number 5
    Issued at 1100 AM AST Fri Aug 18 2017 000 WTNT44 KNHC 181450 TCDAT4 Tropical Storm Harvey Discussion Number 5 NWS National Hurricane Center Miami FL AL092017 1100 AM AST Fri Aug 18 2017 The structure of Harvey has changed little during the past several hours, and overall the storm is poorly organized. The low-level center is near the eastern edge of the convective mass due to the affects of 15 kt of vertical wind shear. In addition, surface observations and Air Force Reserve Hurricane Hunter data suggest that the 850-mb center is located west or southwest of the surface center. Based on the aircraft and surface data, the central pressure is near 1005 mb and the initial intensity remains 35 kt. The initial motion is a quick 270/18. A strong low- to mid-level ridge north of the cyclone should keep Harvey on this general motion for the next 3-4 days, with the system moving from the eastern to the western Caribbean Sea during this time. Late in the forecast period, a more northerly motion is expected when Harvey passes near or over portions of Central America, the Yucatan Peninsula, and eastern Mexico. The new forecast track remains in the center of the guidance, and only minor changes were made to the previous track. The current shear should persist for the next 48 h or so, and thus the intensity forecast continues the trend of slow strengthening during this time. After that, conditions appear favorable for strengthening, with the main uncertainty being how much land Harvey will encounter. The ECMWF keeps the cyclone a little north of Nicaragua and Honduras and allows more room for development, while the GFS forecasts landfall in northeastern Nicaragua and thus has a weaker intensity. The new NHC forecast is close to the previous one in showing a peak intensity below hurricane strength, but the confidence in this portion of the forecast is low.

  • Tropical Depression Thirteen-E Forecast Discussion Number 1
    Issued at 800 AM PDT Fri Aug 18 2017 000 WTPZ43 KNHC 181441 TCDEP3 Tropical Depression Thirteen-E Discussion Number 1 NWS National Hurricane Center Miami FL EP132017 800 AM PDT Fri Aug 18 2017 Deep convection associated with the disturbance located over the open eastern Pacific Ocean has become better organized early this morning, and a primary convective band now wraps around the western half of the circulation. Shortwave-IR and first-light visible imagery suggest that a complex, but closed surface circulation exists. NHC is therefore initiating advisories on Tropical Depression Thirteen-E. The initial intensity is set at 30 kt, in agreement with the max winds measured in an earlier ASCAT pass and the latest Dvorak classification from TAFB. Light easterly vertical wind shear has thus far limited convection to the western half of the circulation, but the GFS and ECMWF agree that the shear will lessen as the system moves farther west. Overall, the environment appears conducive for intensification for the next 3 days or so, and the NHC forecast indicates that the cyclone will become a hurricane by the end of this weekend. After that time, the cyclone will begin to weaken over much cooler waters. The NHC forecast is very close to the multi-model consensus, IVCN. Since the center has only recently formed, the initial motion estimate is a fairly uncertain 285/13 kt. There is fairly good agreement among the global models that the tropical cyclone will move generally westward to west-northwestward for the next 72 h along the southern boundary of a mid-level ridge that extends westward well into the eastern Pacific basin. A weakness in the ridge is forecast to develop in about 3 days that should cause the cyclone to slow and turn more toward the northwest and eventually toward the north-northwest. The official forecast is close to a blend of the GFS and ECMWF models.
