TROPICAL STORM ODALYS ADVISORY / FORECAST
ADVISORY from National Hurricane Center:
...ODALYS BECOMES A REMNANT LOW.. ...THIS IS THE LAST ADVISORY... SUMMARY OF 700 PM PST...0300 UTC...INFORMATION ---------------------------------------------- LOCATION...18.6N 124.3W ABOUT 975 MI...1570 KM WSW OF THE SOUTHERN TIP OF BAJA CALIFORNIA MAXIMUM SUSTAINED WINDS...35 MPH...55 KM/H PRESENT MOVEMENT...W OR 270 DEGREES AT 8 MPH...13 KM/H MINIMUM CENTRAL PRESSURE...1005 MB...29.68 INCHES WATCHES AND WARNINGS -------------------- There are no coastal watches or warnings in effect. DISCUSSION AND OUTLOOK ---------------------- At 700 PM PST (0300 UTC), the center of Post-Tropical Cyclone Odalys was located near latitude 18.6 North, longitude 124.3 West. The post-tropical cyclone is moving toward the west near 8 mph (13 km/h). This motion is expected to continue tonight, followed by a turn toward to the west-southwest by Friday afternoon. Maximum sustained winds have decreased to near 35 mph (55 km/h) with higher gusts. Additional weakening is forecast over the next couple of days, and Odalys is expected to dissipate over the weekend. The estimated minimum central pressure is 1005 mb (29.68 inches). HAZARDS AFFECTING LAND ---------------------- None. NEXT ADVISORY ------------- This is the last public advisory issued by the National Hurricane Center on Odalys.

DISCUSSION from National Hurricane Center:
Expires:No;;394327 WTPZ45 KNHC 060232 TCDEP5 Post-Tropical Cyclone Odalys Discussion Number 10 NWS National Hurricane Center Miami FL EP202020 700 PM PST Thu Nov 05 2020 Odalys has been devoid of any significant convection within 100 n mi 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 kt 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 kt. An earlier 1725Z ASCAT-A pass contained a small patch of 34-kt 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-deg-C sea-surface temperatures and within a very hostile vertical wind shear regime. The shear is expected to increase from the current 35 kt to more than 40 kt 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 kt. 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.
