066 FZPN27 KNHC 191710 AAA OFFPZ7 Offshore Waters Forecast...UPDATED NWS National Hurricane Center Miami, FL 1010 AM PDT Thu Oct 19 2023 Offshore Waters Forecast for the E Pacific within 250 nm of Mexico Updated for latest Forecast on Norma 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. PMZ001-200515- Synopsis for the E Pacific within 250 nm of Mexico 1010 AM PDT Thu Oct 19 2023 .SYNOPSIS...Hurricane Norma is near 17.4N 107.6W at 8 AM PDT, and is moving north at 6 kt. Maximum sustained winds are 115 kt with gusts to 140 kt, and the minimum central pressure is 946 mb. Norma will move to 18.1N 107.7W this evening, 19.3N 108.3W Fri morning, 20.5N 108.8W Fri evening, 21.9N 109.2W Sat morning, 23.0N 109.3W Sat evening, and weaken to a tropical storm near 23.6N 109.0W Sun morning. Norma will change little in intensity as it moves to 24.2N 108.3W early Mon. Elsewhere, fresh to strong N winds will continue to pulse over the Tehuantepec region through Sat morning. Gentle to moderate winds will prevail elsewhere through the end of the week. Fresh to strong winds offshore Baja California may develop this weekend. Large NW swell is forecast to spread offshore Baja California later today into the weekend, resulting in confused and hazardous seas as it mixes with swells generated by Norma. A new set of NW swell may spread offshore Baja California early next week. Meanwhile, an area of low pres, EP91, located several hundred nautical miles south of the Gulf of Tehuantepec near 08.5N94.5W is expected to gradually develop, and a tropical depression is likely to form during the next few days while the system meanders or drifts generally northward over the far eastern portion of the basin. This system has a medium chance of tropical cyclone formation through 48 hours, and a high chance through 7 days. $$ PMZ009-200515- Mexico Border S to 29N within 60 nm of shore- 1010 AM PDT Thu Oct 19 2023 .TODAY...NW winds 15 to 20 kt in the afternoon.
