Issued at 1100 PM AST Fri Oct 01 2021 000 WTNT35 KNHC 020242 TCPAT5 BULLETIN Tropical Storm Victor Advisory Number 11 NWS National Hurricane Center Miami FL AL202021 1100 PM AST Fri Oct 01 2021 ...DISORGANIZED VICTOR WEAKENING OVER THE EASTERN TROPICAL ATLANTIC... SUMMARY OF 1100 PM AST...0300 UTC...INFORMATION ----------------------------------------------- LOCATION...12.3N 35.3W ABOUT 800 MI...1285 KM WSW OF THE CABO VERDE ISLANDS MAXIMUM SUSTAINED WINDS...60 MPH...95 KM/H PRESENT MOVEMENT...WNW OR 290 DEGREES AT 13 MPH...20 KM/H MINIMUM CENTRAL PRESSURE...999 MB...29.50 INCHES WATCHES AND WARNINGS -------------------- There are no coastal watches or warnings in effect. DISCUSSION AND OUTLOOK ---------------------- At 1100 PM AST (0300 UTC), the center of Tropical Storm Victor was located near latitude 12.3 North, longitude 35.3 West. Victor is moving toward the west-northwest near 13 mph (20 km/h) and this general motion is expected to continue with a gradual turn more northwest over the next several days. Maximum sustained winds have decreased to near 60 mph (95 km/h) with higher gusts. Additional weakening is forecast during the next few days, and Victor is now forecast to become a remnant low Monday night. Tropical-storm-force winds extend outward up to 140 miles (220 km) from the center. The estimated minimum central pressure is 999 mb (29.50 inches). HAZARDS AFFECTING LAND ---------------------- None. NEXT ADVISORY ------------- Next complete advisory at 500 AM AST. $$ Forecaster Papin

Tropical Storm Victor Forecast Discussion Number 10
2021-10-01 22:43:32| National Hurricane Center (Atlantic)
Issued at 500 PM AST Fri Oct 01 2021 000 WTNT45 KNHC 012043 TCDAT5 Tropical Storm Victor Discussion Number 10 NWS National Hurricane Center Miami FL AL202021 500 PM AST Fri Oct 01 2021 Victor is looking disorganized. Deep convection has decreased in organization and coverage this afternoon. No recent microwave imagery has been available to assess the structure of the storm, but visible images from MET-11 and GOES-17 suggest that the circulation of the tropical storm is still elongated southwest-to-northeast. The intensity estimate remains 55 kt for this advisory, but this is on the high end of the recent estimates and could be generous. Compared to the large changes made this morning, almost no change was made to the official track forecast this afternoon. The model consensus has shifted substantially back to the right, and now lies very near the previous NHC forecast. Victor is forecast to turn northwestward tomorrow, and then continue on that heading through early next week, steered by ridging to the northeast. The new NHC forecast is very near the model consensus through the end of the forecast. Despite the recent agreement between the NHC forecast and the consensus, confidence in the forecast will remain low until we see better run-to-run consistency in the track model guidance. Shear and dry air may already be taking a toll on Victor, and SHIPS diagnostics from the GFS and ECMWF suggest that the environment will get worse with time. All of the intensity models forecast that Victor will weaken over the next several days in response to the hostile environment, and this is reflected in the NHC forecast, which is heavily based on the IVCN multi-model consensus. By day 5, all of the dynamical models indicate that Victor will likely degenerate into a trough of low pressure, so dissipation is shown. Several models, including the HWRF, GFS, and ECMWF indicate dissipation could occur sooner than that.
