Issued at 500 PM AST Mon Sep 09 2019 000 WTNT33 KNHC 092033 TCPAT3 BULLETIN Tropical Storm Gabrielle Advisory Number 26 NWS National Hurricane Center Miami FL AL082019 Issued by the NWS Weather Prediction Center College Park MD 500 PM AST Mon Sep 09 2019 ...GABRIELLE ACCELERATING NORTHEASTWARD OVER THE NORTH ATLANTIC... SUMMARY OF 500 PM AST...2100 UTC...INFORMATION ---------------------------------------------- LOCATION...40.7N 45.4W ABOUT 1000 MI...1605 KM WNW OF THE AZORES MAXIMUM SUSTAINED WINDS...50 MPH...85 KM/H PRESENT MOVEMENT...NE OR 40 DEGREES AT 21 MPH...33 KM/H MINIMUM CENTRAL PRESSURE...1000 MB...29.53 INCHES WATCHES AND WARNINGS -------------------- There are no coastal watches or warnings in effect. DISCUSSION AND OUTLOOK ---------------------- At 500 PM AST (2100 UTC), the center of Tropical Storm Gabrielle was located near latitude 40.7 North, longitude 45.4 West. Gabrielle is moving toward the northeast near 21 mph (33 km/h), and this general motion with an increase in forward speed is forecast over the next couple of days. Maximum sustained winds are near 50 mph (85 km/h) with higher gusts. Little change in strength is expected tonight, but a weakening trend is likely to begin Tuesday. Gabrielle is expected to become an extratropical low by Tuesday night and dissipate over the far North Atlantic Thursday. Tropical-storm-force winds extend outward up to 115 miles (185 km) from the center. The estimated minimum central pressure is 1000 mb (29.53 inches). HAZARDS AFFECTING LAND ---------------------- None. NEXT ADVISORY ------------- Next complete advisory at 1100 PM AST. $$ Forecaster Taylor/Blake

Tropical Storm Gabrielle Forecast Discussion Number 25

Issued at 1100 AM AST Mon Sep 09 2019 ZCZC MIATCDAT3 ALL TTAA00 KNHC DDHHMM Tropical Storm Gabrielle Discussion Number 25 NWS National Hurricane Center Miami FL AL082019 Issued by the NWS Weather Prediction Center College Park MD 1100 AM AST Mon Sep 09 2019 Satellite images indicate that deep convection has increased overnight and become more symmetric around the center of Gabrielle. Still, ASCAT data show maximum winds of only about 40 kt, suggestive that this convective burst hasn't changed the intensity much. The initial wind speed is set to 45 kt, near the TAFB satellite estimate and a little above the ASCAT data to account for undersampling. Gabrielle has turned northeastward and picked up some speed. The system is expected to move at an increasing pace in a similar direction over the next few days as it is picked up by a mid-latitude trough. Model guidance is tightly clustered around the previous NHC prediction, and no significant changes were made to the prior NHC track forecast. The storm has about a day over marginally warm waters before it crosses the north wall of the Gulf Stream into much colder waters. Gabrielle is forecast to transition into an extratropical low by Tuesday due to an increase in shear and baroclinicity from an approaching cold front. The intensity forecast was reduced slightly from the previous one and is in close agreement with a blend of the GFS/ECMWF wind speed forecasts, which should best handle this extratropical transition scenario.
