487 FZPN27 KNHC 210952 OFFPZ7 Offshore Waters Forecast NWS National Hurricane Center Miami, FL 252 AM PDT Sat Oct 21 2023 Offshore Waters Forecast for the E Pacific within 250 nm of Mexico Seas given as significant wave height, which is the average height of the highest 1/3 of the waves. Individual waves may be more than twice the significant wave height. PMZ001-212200- Synopsis for the E Pacific within 250 nm of Mexico 252 AM PDT Sat Oct 21 2023 .SYNOPSIS...Major Hurricane Norma is near 21.7N 110.1W at 2 AM PDT, and is moving north at 8 kt. Maximum sustained winds are 100 kt with gusts to 120 kt, and the minimum central pressure is 958 mb. Norma will move to 22.7N 110.1W this afternoon, inland to 23.5N 109.7W Sun morning, 23.9N 109.0W Sun afternoon, weaken to a tropical storm near 24.2N 108.1W Mon morning, inland to 24.7N 107.0W Mon afternoon, and Tue morning. Strong winds over the Gulf of Tehuantepec will diminish this afternoon. Fresh to locally strong winds can be expected across the Baja California offshore waters N of Cabo San Lazaro through Sun along with large NW swell. This will result in confused and hazardous seas as it mixes with swells generated by Norma. A new set of NW swell is forecast to enter the offshores of Baja California again next week. A broad area of low pressure located well south of the Gulf of Tehuantepec has the potential to develop into a tropical depression later this weekend or early next week. $$ PMZ009-212200- Mexico Border S to 29N within 60 nm of shore- 252 AM PDT Sat Oct 21 2023 .TODAY...NW winds 20 to 25 kt.
