Tropical Storm Iselle Public Advisory Number 12
2020-08-29 10:37:15| National Hurricane Center (East Pacific)
Issued at 200 AM PDT Sat Aug 29 2020 000 WTPZ34 KNHC 290837 TCPEP4 BULLETIN Tropical Storm Iselle Advisory Number 12 NWS National Hurricane Center Miami FL EP142020 200 AM PDT Sat Aug 29 2020 ...ISELLE EXPECTED TO WEAKEN TO A TROPICAL DEPRESSION TONIGHT... SUMMARY OF 200 AM PDT...0900 UTC...INFORMATION ---------------------------------------------- LOCATION...19.7N 115.1W ABOUT 400 MI...645 KM WSW OF THE SOUTHERN TIP OF BAJA CALIFORNIA MAXIMUM SUSTAINED WINDS...45 MPH...75 KM/H PRESENT MOVEMENT...N OR 10 DEGREES AT 6 MPH...9 KM/H MINIMUM CENTRAL PRESSURE...1001 MB...29.56 INCHES WATCHES AND WARNINGS -------------------- There are no coastal watches or warnings in effect. DISCUSSION AND OUTLOOK ---------------------- At 200 AM PDT (0900 UTC), the center of Tropical Storm Iselle was located near latitude 19.7 North, longitude 115.1 West. Iselle is moving toward the north near 6 mph (9 km/h). A northward motion is expected to continue for another day or so, followed by a turn to the northwest. Maximum sustained winds are near 45 mph (75 km/h) with higher gusts. Additional weakening is forecast, and Iselle is expected to become a tropical depression tonight. The depression should then degenerate into a remnant low on Sunday. Tropical-storm-force winds extend outward up to 45 miles (75 km) from the center. The estimated minimum central pressure is 1001 mb (29.56 inches). HAZARDS AFFECTING LAND ---------------------- SURF: Swells generated by Iselle and a large area of southwesterly winds to its south are affecting portions of the southwestern and west-central coast of Mexico, as well as the west coast of Baja California Sur. These swells are expected to continue for the next couple of days and will likely cause life-threatening surf and rip current conditions. Please consult products from your local weather office. NEXT ADVISORY ------------- Next complete advisory at 800 AM PDT. $$ Forecaster Cangialosi
