SUMMARY OF 1100 PM HST...0900 UTC...INFORMATION ----------------------------------------------- LOCATION...15.9N 136.3W ABOUT 1265 MI...2030 KM E OF HILO HAWAII MAXIMUM SUSTAINED WINDS...45 MPH...75 KM/H PRESENT MOVEMENT...W OR 265 DEGREES AT 15 MPH...24 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 1100 PM HST (0900 UTC), the center of Tropical Storm Felicia was located near latitude 15.9 North, longitude 136.3 West. Felicia is moving toward the west near 15 mph (24 km/h). A westward to west-southwestward motion is expected during the next few days. Satellite-derived wind data indicate that maximum sustained winds have decreased to near 45 mph (75 km/h) with higher gusts. Additional weakening is expected during the next couple of days. Felicia is forecast to become a tropical depression on Tuesday and degenerate into a remnant low by Wednesday. Tropical-storm-force winds extend outward up to 45 miles (75 km), mainly to the north of the center. The estimated minimum central pressure is 1005 mb (29.68 inches). HAZARDS AFFECTING LAND ---------------------- None. NEXT ADVISORY ------------- Next complete advisory at 500 AM HST. $$ Forecaster Reinhart/Pasch

Tropical Storm Felicia Forecast Discussion Number 24
2021-07-20 04:37:31| National Hurricane Center (East Pacific)
Issued at 500 PM HST Mon Jul 19 2021 423 WTPZ41 KNHC 200237 TCDEP1 Tropical Storm Felicia Discussion Number 24 NWS National Hurricane Center Miami FL EP062021 500 PM HST Mon Jul 19 2021 Felicia continues to rapidly weaken over sea-surface temperatures (SST) of around 25 deg C and within a cooler and drier air mass. After an earlier burst of strong convection, all that remains of it is limited to the northeastern quadrant along with cloud tops now having warmed to -55C to -60C. The latest satellite intensity estimates from TAFB and SAB were 45 kt, and that is the intensity assigned for this advisory. Additional weakening is forecast through the remainder of the 72-h forecast period due to the cyclone remaining over SSTs near 25C, westerly vertical wind shear increasing to more than 30 kt by 24 hours, and continued entrainment of drier and cooler low- to mid-level air. The new NHC intensity forecast is similar to the previous advisory, and closely follows a blend of the IVCN and HCCA intensity consensus models. The initial motion estimate remains a little south of due west, or 265/13 kt. A low- to mid-level subtropical ridge to the north of the cyclone is expected to steer Felicia west-southwestward to westward over the next few days until the small cyclone dissipates by 96 hours, if not sooner. Felicia will likely cross into the Central Pacific basin by Tuesday night. The new official track forecast is similar to the previous advisory track, and lies between the tightly packed TVCE and NOAA-HCCA track forecast models.
