000 WTPA33 PHFO 201440 TCPCP3 BULLETIN Post-Tropical Cyclone Linda Advisory Number 42 NWS Central Pacific Hurricane Center Honolulu HI EP122021 500 AM HST Fri Aug 20 2021 ...LINDA BECOMES POST-TROPICAL EAST OF HAWAII... ...THIS IS THE LAST ADVISORY... SUMMARY OF 500 AM HST...1500 UTC...INFORMATION ---------------------------------------------- LOCATION...20.3N 144.0W ABOUT 720 MI...1160 KM E OF HILO HAWAII ABOUT 900 MI...1450 KM E OF HONOLULU HAWAII MAXIMUM SUSTAINED WINDS...40 MPH...65 KM/H PRESENT MOVEMENT...W OR 280 DEGREES AT 17 MPH...28 KM/H MINIMUM CENTRAL PRESSURE...1006 MB...29.71 INCHES WATCHES AND WARNINGS -------------------- There are no coastal watches or warnings in effect. Although Linda has become post-tropical, remnants of the system are expected to impact portions of the main Hawaiian Islands Sunday and Monday. Interests in Hawaii should monitor the progress of the remnant low. DISCUSSION AND OUTLOOK ---------------------- At 500 AM HST (1500 UTC), the center of Post-Tropical Cyclone Linda was located near latitude 20.3 North, longitude 144.0 West. The post-tropical cyclone is moving toward the west near 17 mph (28 km/h), and this general motion is expected to continue for the next few days, with some slowing in forward speed tonight and Saturday. Maximum sustained winds are near 40 mph (65 km/h) with higher gusts. Little change in strength is forecast during the next 48 hours, with weakening expected thereafter. Dissipation is expected early next week. Tropical-storm-force winds extend outward up to 80 miles (130 km) from the center. The estimated minimum central pressure is 1006 mb (29.71 inches). HAZARDS AFFECTING LAND ---------------------- SURF: Swells generated by Linda will affect east facing shores of the main Hawaiian Islands over the next couple of days. Please consult products from the National Weather Service's Honolulu Forecast Office. NEXT ADVISORY ------------- This is the last public advisory issued by the Central Pacific Hurricane Center on Linda. Future information on this system can be found in forecasts issued by the National Weather Service in Honolulu, on the web at http://weather.gov/hfo. $$ Forecaster Birchard

000 WTPA43 PHFO 201445 TCDCP3 Post-Tropical Cyclone Linda Discussion Number 42 NWS Central Pacific Hurricane Center Honolulu HI EP122021 500 AM HST Fri Aug 20 2021 Linda's time as a tropical cyclone has come to an end. Infrared and VIIRS day-night satellite imagery depict an elongating low cloud swirl, and deep convection has been absent over the center for nearly 24 hours, thus Linda is deemed to be post-tropical. The initial intensity estimate of 35 kt for this advisory remains heavily influenced by a recent scatterometer pass that indicated winds to 40 kt north of the center. The initial motion estimate is 280/15 kt, with Linda being steered by a persistent low- to mid-level ridge to the north. Tightly- clustered track guidance indicates that the ridge will continue to drive the post-tropical remains of Linda toward the west, with a slight reduction in forward speed tonight and Saturday. The guidance has trended southward over the last couple of days, and the official forecast indicates that remnants of Linda will impact portions of the main Hawaiian Islands Sunday and Monday, in line with the corrected consensus guidance HCCA, and the GEFS mean. Compared to the recent rapid weakening, a relatively slow rate of decay of the wind field is expected over the next couple of days. As the system gradually spins down, gale force winds north of the center will be slow to diminish, due to the gradient between the high to the north and the remnant low. Some sporadic deep convection may also occur, but the combined effects of dry air in the mid- and upper-levels and increasing vertical wind shear will prevent regeneration into a tropical cyclone, and lead to system dissipation by day 4. This is supported by the reliable global models, as well as the intensity consensus IVCN. This is the last advisory issued by the Central Pacific Hurricane Center on Linda.
