SUMMARY OF 1100 AM HST...2100 UTC...INFORMATION ----------------------------------------------- LOCATION...19.1N 130.3W ABOUT 1340 MI...2155 KM W OF THE SOUTHERN TIP OF BAJA CALIFORNIA MAXIMUM SUSTAINED WINDS...40 MPH...65 KM/H PRESENT MOVEMENT...W OR 260 DEGREES AT 17 MPH...28 KM/H MINIMUM CENTRAL PRESSURE...1003 MB...29.62 INCHES WATCHES AND WARNINGS -------------------- There are no coastal watches or warnings in effect. DISCUSSION AND OUTLOOK ---------------------- At 1100 AM HST (2100 UTC), the center of Post-Tropical Cyclone Irwin was located near latitude 19.1 North, longitude 130.3 West. The post-tropical cyclone is moving toward the west near 17 mph (28 km/h). This general motion with a gradual decrease in forward speed is expected over the next few days. Satellite wind data indicate that maximum sustained winds are near 40 mph (65 km/h) with higher gusts. Gradual weakening is forecast during the next few days. Tropical-storm-force winds extend outward up to 70 miles (110 km) to the northwest of the center. The estimated minimum central pressure is 1003 mb (29.62 inches). HAZARDS AFFECTING LAND ---------------------- None NEXT ADVISORY ------------- This is the last public advisory issued by the National Hurricane Center on Irwin. For additional information on the post-tropical cyclone, please see High Seas Forecasts issued by the National Weather Service, under AWIPS header NFDHSFEPI, WMO header FZPN02 KWBC, and on the web at ocean.weather.gov/shtml/NFDHSFEPI.php $$ Forecaster Reinhart

Post-Tropical Cyclone IRWIN Forecast Discussion
000 WTPZ45 KNHC 292035 TCDEP5 Post-Tropical Cyclone Irwin Discussion Number 12 NWS National Hurricane Center Miami FL EP102023 1100 AM HST Tue Aug 29 2023 Irwin has failed to produce any convection near its center during the last 15-18 h. Since it no longer satisfies the criteria of a tropical cyclone, Irwin is being designated as a post-tropical cyclone with this advisory. A recent scatterometer pass showed a broad area of winds at or slightly above 30 kt in the northwestern quadrant, and so the initial intensity remains 35 kt. The post-tropical cyclone is moving slightly south of due west (260/15 kt). A general westward motion at a gradually slower forward speed is expected over the next several days while Irwin is steered by a low-level ridge over the eastern Pacific. Gradual weakening is forecast as the shallow cyclone spins down over cooler waters and in a drier, more stable environment. While some intermittent bursts of convection could occur during the next couple of days, the overall environment does not appear conducive for Irwin to regenerate to a tropical cyclone. This is the last NHC advisory on Irwin.
