Tropical Storm Odalys 2020

Satellite images, weather maps and tracks of Tropical Storm Odalys 2020, November 1 - 7. Max wind speed 50mph.

Odalys has been devoid of any significant convection within 100 nautical miles of the center for more than 12 hours, and the system no longer meets the satellite-based criteria of a tropical cyclone. The initial intensity of 30 knots is based on an expected gradual spin down of the circulation, which is supported by a Dvorak current-intensity satellite classification of T2.0/30 knots. An earlier 17:25 UTC ASCAT-A pass contained a small patch of 34-knot winds located northwest of the center, and there is currently no convection in that same sector of the cyclone. Post-tropical Odalys is currently located over marginal 26°C sea-surface temperatures and within a very hostile vertical wind shear regime. The shear is expected to increase from the current 35 knots to more than 40 knots by 24 hours, which should prevent any significant and/or persistent convection from redeveloping near the low-level center. As a result, Odalys should continue to weaken and dissipate by 72 hours, if not sooner.

The initial motion estimate is 270/07 knots. A westward motion should continue tonight, followed by a turn toward the west-southwest or southwest by Friday afternoon, with that motion continuing into the weekend until Odalys dissipates. The NHC official forecast track is similar to the previous advisory track, and lies close to the consensus track model TVCE.

This is the last advisory issued by the National Hurricane Center on Odalys.
