000 FZPN27 KNHC 202147 OFFPZ7 Offshore Waters Forecast NWS National Hurricane Center Miami, FL 247 PM PDT Fri Oct 20 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. PMZ001-211000- Synopsis for the E Pacific within 250 nm of Mexico 247 PM PDT Fri Oct 20 2023 .SYNOPSIS...Major Hurricane Norma is near 20.1N 109.8W at 2 PM PDT, and is moving north-northwest at 7 kt. Maximum sustained winds are 105 kt with gusts to 115 kt, and the minimum central pressure is 955 mb. Norma will move to 21.2N 110.0W Sat morning, 22.6N 110.1W Sat afternoon, 23.4N 109.7W Sun morning, weaken to a tropical storm near 23.9N 109.0W Sun afternoon, 24.2N 108.1W Mon morning, and inland to 24.6N 107.1W Mon afternoon. Norma will dissipate Tue afternoon. Meanwhile, strong winds over the Gulf of Tehuantepec will diminish by Sat afternoon. Fresh to locally strong winds can be expected across the Baja California offshore waters this weekend. Large NW swell is forecast to continue to persist across offshore Baja California through most of the weekend, resulting in confused and hazardous seas as it mixes with swells generated by Norma. The swell will begin to subside by Sunday, with a new set of NW swell entering the offshores of Baja California early next week. A broad area of low pressure is located well south of the Gulf of Tehuantepec. The environmental conditions are expected to become more conducive for this low to develop over the next couple of days. A tropical depression is likely to form later this weekend or early next week. The system is forecast to meander during the next couple of days and then drift generally northward late this weekend and into early next week. This system has a medium chance of tropical cyclone formation through 48 hours, and a high chance through 7 days. $$ PMZ009-211000- Mexico Border S to 29N within 60 nm of shore- 247 PM PDT Fri Oct 20 2023 .TONIGHT...NW winds 20 to 25 kt.
