Tropical Storm Olaf Forecast Discussion Number 6
2021-09-09 04:37:57| National Hurricane Center (East Pacific)
Issued at 900 PM MDT Wed Sep 08 2021 000 WTPZ45 KNHC 090237 TCDEP5 Tropical Storm Olaf Discussion Number 6 NWS National Hurricane Center Miami FL EP152021 900 PM MDT Wed Sep 08 2021 Olaf appears to be gradually strengthening. Deep convection has been increasing over the center, and banding features are becoming a little more pronounced. The latest Dvorak estimates range from 35 to 45 kt. Since the system appears to be better organized from the time of the ASCAT pass earlier today, the initial intensity is nudged up and set near the high end of the estimates at 45 kt. Satellite images and recent microwave data suggest that the center of Olaf is a little to the east of the previous track, and the latest initial motion estimate is 335/6 kt. Olaf is expected to move generally northwestward for another 24 to 36 hours, which should bring the system just off the coast of southern Baja California Sur during that time. There is some spread in the models on how close the storm will get to the coastline, with the GFS to the east of the official forecast and the UKMET and ECMWF to the west and farther offshore. Beyond 36 hours, Olaf is expected to be located to the south of a strong mid-level ridge and that will cause a turn to the west-northwest away from Mexico. The NHC track forecast is adjusted again to the east of the previous one in the short term and then to the south of the previous one at the longer lead times. The new track forecast lies near the middle of the guidance envelope, near the various consensus aids. Olaf is located over warm waters, and embedded in a low wind shear and fairly moist environment. These conditions should allow for additional strengthening during the next day or so. Although not explicitly forecast, Olaf could become a hurricane when it is just off the coast of southern Baja California Sur, and a hurricane watch remains in effect for the possibility of those winds occurring on land. By Friday, a combination of cooler waters and a much drier environment should cause steady weakening, and the system is likely to become a remnant low over the weekend. The NHC intensity forecast lies close to the IVCN and IVDR consensus models. Key Messages: 1. Olaf is forecast to strengthen to near hurricane intensity while it passes offshore of the southern portion of Baja California Sur Thursday and Friday. Tropical storm conditions are expected and hurricane conditions are possible across that area beginning late Thursday. Interests there should continue to monitor the progress of Olaf. 2. Heavy rains associated with Tropical Storm Olaf are possible across portions of far southern Baja California Sur Thursday through Friday. This will pose a threat of flash flooding and mudslides.

SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Hurricane Watch is in effect for... * Baja California Sur Mexico from Cabo San Lucas to Todos Santos A Tropical Storm Warning is in effect for... * Baja California Sur Mexico from Los Barriles to Santa Fe A Hurricane Watch means that hurricane conditions are possible within the watch area. A watch is typically issued 48 hours before the anticipated first occurrence of tropical-storm-force winds, conditions that make outside preparations difficult or dangerous. A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area within 36 hours. Interests elsewhere in Baja California Sur should monitor the progress of Olaf. For storm information specific to your area, please monitor products issued by your national meteorological service. DISCUSSION AND OUTLOOK ---------------------- At 900 PM MDT (0300 UTC), the center of Tropical Storm Olaf was located near latitude 20.0 North, longitude 108.0 West. Olaf is moving toward the north-northwest near 7 mph (11 km/h). A northwest to north-northwest motion along with an increase in forward speed is expected through Friday. A turn toward the west-northwest is forecast by Friday night, followed by a turn toward the west on Saturday. On the forecast track, the center of Olaf will move just to the southwest of southern Baja California Sur on Thursday and Friday. Maximum sustained winds have increased to near 50 mph (85 km/h) with higher gusts. Additional strengthening is forecast during the next day or so, and Olaf could be near hurricane strength by late Thursday. The storm is expected to begin weakening on Friday. Tropical-storm-force winds extend outward up to 70 miles (110 km) from the center. The estimated minimum central pressure is 1000 mb (29.53 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Tropical Storm Olaf can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDEP5 and WMO header WTPZ45 KNHC and on the web at hurricanes.gov/graphics_ep5.shtml?key_messages WIND: Hurricane conditions are possible within the Hurricane Watch area in Baja California Sur Thursday night. Tropical storm conditions are expected in the Tropical Storm Warning area in Baja California Sur by late Thursday or Thursday night. RAINFALL: Olaf is expected to produce total rainfall amounts of 3 to 6 inches with maximum amounts of 10 inches across portions of far southern Baja California Sur Thursday through Friday. This rainfall may trigger flash flooding and mudslides. SURF: Olaf is expected to generate swells that will affect portions of the coasts of Baja California Sur and Sinaloa by Thursday, spreading northward along the west coast of Baja California Sur through Friday. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office. NEXT ADVISORY ------------- Next intermediate advisory at 1200 AM MDT. Next complete advisory at 300 AM MDT. $$ Forecaster Cangialosi
