DISCUSSION AND OUTLOOK ---------------------- At 1100 AM AST (1500 UTC), the center of Tropical Storm Victor was located near latitude 13.1 North, longitude 37.2 West. Victor is moving toward the northwest near 12 mph (19 km/h), and this general motion is expected to continue over the next few days. Maximum sustained winds are near 40 mph (65 km/h) with higher gusts. Gradual weakening is forecast over the next couple of days, and Victor could become a remnant low by tonight. The system is then forecast to dissipate by Tuesday. Tropical-storm-force winds extend outward up to 115 miles (185 km) from the center. The estimated minimum central pressure is 1005 mb (29.68 inches). HAZARDS AFFECTING LAND ---------------------- None.

Tropical Storm Victor Forecast Discussion Number 12
2021-10-02 10:42:34| National Hurricane Center (Atlantic)
Issued at 500 AM AST Sat Oct 02 2021 118 WTNT45 KNHC 020842 TCDAT5 Tropical Storm Victor Discussion Number 12 NWS National Hurricane Center Miami FL AL202021 500 AM AST Sat Oct 02 2021 Victor's satellite appearance has continued to degrade this morning with the closest convection now located more than 150 nmi northeast of the fully exposed low-level circulation center. Thus, Victor no longer technically meets the convective criterion of a tropical cyclone. However, tropical cyclone status is being maintained for this advisory out of continuity with the previous advisory and just in case a burst of deep convection redevelops later today near the still-well-defined low-level circulation center. Victor's intensity has been lowered to 45 kt based on a subjective Dvorak current intensity estimate of CI3.0/45 kt from TAFB, and the typical decay rate and spin down of a non-convective vortex over open water. The motion estimate remains west-northwestward, or 300/11 kt. Victor is forecast to move west-northwestward to northwestward around the southwestern periphery of a deep-layer subtropical ridge for the next 72-96 hours or until dissipation occurs. The new NHC forecast track is similar to the previous advisory track, and lies close to the tightly packed simple- and corrected-consensus track models. Deep-layer south-southwesterly vertical wind shear of around 20 kt and entrainment of dry mid-level air have taken their toll on Victor. These unfavorable environmental parameters are expected to worsen, resulting in continued weakening throughout the forecast period. Therefore, Victor is forecast to become a tropical depression by Sunday, degenerate into a remnant low by Monday, and dissipate by Wednesday. However, the current weakening trend will be hastened if organized convection does not return within the next 12 hours. The new official intensity forecast is a little lower than the previous advisory, and is also lower than most of the intensity guidance due to Victor's aforementioned severely degraded convective pattern.
