The following information is based on satellite imagery, weather observations, radar, and meteorological analysis. Based on 1200 UTC surface analysis and satellite imagery through 1500 UTC. ...SPECIAL FEATURES... Scattered showers and thunderstorms located several hundred nautical miles southwest of the coast of southwestern Mexico are associated with an 1010 mb area of low pressure near 13.5N114.5W 1010 MB. Scattered moderate to strong convection is noted from 12N to 17N between 113W and 117W. Current winds are 20 to 30 kt with seas of 8 to 9 ft. While this system still lacks a well- defined circulation, environmental conditions remain generally conducive for development, and a tropical depression could still form over the next couple of days. This system is moving towards the west- northwest at 10 to 15 kt and will be moving towards cooler waters by this weekend, where additional development is unlikely after that time. There is a medium chance of tropical cyclone formation within the next 48 hours.

Please refer to the Special Features section for details on Atlantic Potential Tropical Cyclone Two which is forecast to move across the offshore Gulf of Tehuantepec waters Sun and Sun night, continuing west-northwest offshore Mexico thereafter. Fresh to strong N to NE winds are in the Gulf of Tehuantepec. Gentle to moderate winds prevail over the remainder of the area. Seas are 4 to 6 ft across the offshore waters, and 1 to 3 ft in the Gulf of California north of the entrance. For the forecast, other than Atlantic Potential Tropical Cyclone Two, fresh to strong N-NE winds in the Gulf of Tehuantepec will diminish to moderate to fresh this afternoon through Fri morning. Winds offshore of Baja California north of Cabo San Lazaro will increase and pulse to moderate to fresh by the end of the week into the weekend, while a moderate NW swell builds across the same area.

Seas are mainly 4 to 6 ft across the offshore waters in southerly swell, except 2 to 4 ft in and near the Gulf of Panama. For the forecast, other than Atlantic Potential Tropical Cyclone Two, moderate to fresh pulsing NE to E winds will pulse in the Papagayo region through Fri morning with little change elsewhere through the next several days. REMAINDER OF THE AREA... Please refer to the Special Features section for details on a small low pressure system centered a few hundred nautical miles southwest of the coast of southwestern Mexico. The remnant 1014 mb low of Celia is located near 24.5N1256W with no deep convection, moderate winds, and seas around 7 ft. Winds will continue to diminish as the remnant low opens into a trough over the next day or two. High pressure dominates the remainder of the forecast waters north of the ITCZ and monsoon trough. Moderate to locally fresh winds are west of a line from 30N122W to 18N140W. Gentle to moderate winds prevail elsewhere.
