The following information is based on satellite imagery, weather observations, radar, and meteorological analysis. Based on 0000 UTC surface analysis and satellite imagery through 0300 UTC. ...SPECIAL FEATURES... Hurricane Simon is centered near 20.1N 107.6W at 14/0300 UTC, moving west at 2 kt. Estimated minimum central pressure is 965 mb. Maximum sustained wind speed is 95 kt with gusts to 115 kt. Peak seas are near 20 ft. Numerous moderate to strong convection is within 30 nm of the center. Scattered to numerous moderate and isolated strong convection is elsewhere from 18N to 21N between 106W and 109W. Simon remains a small hurricane, but has started to re intensify. Simon is located in an area of weak steering currents and is forecast to drift southwestward over the next couple of days. Simon could be near Las Islas Marias on Thursday, where a Hurricane Watch remains in effect. Interests in west- central Mexico and Baja California Sur should continue to closely monitor the latest updates. Additional watches or warnings could be required over the next day or two. Simon is expected to produce rainfall totals of 1 to 2 inches with isolated maximum amounts of 3 inches over portions of the states of Baja California Sur, Nayarit, and Sinaloa. Large swells generated by Simon will likely affect portions of the coast of west- central Mexico and Baja California Sur over the next several days. These swells are likely to cause large and powerful surf and life- threatening rip current conditions. Please consult products from your local weather office.

Peak seas are estimated at 13 ft across the N semicircle. Scattered to numerous moderate to strong convection is occurring from 09N to 5N between 92W and 100W. The initial motion of Trudy is northwestward, and a general northwestward to west-northwestward motion is forecast through 72 hr. Trudy is forecast to reach hurricane intensity within the next 24 hours, and is forecast to be a major hurricane as it approaches the coast of southwestern and west-central Mexico late this week and into the weekend. There is an increasing risk of wind, rain, and storm surge impacts, and watches could be required for a portion of these areas on Wednesday. Swells generated by Trudy will affect portions of the coast of southwestern Mexico the end of the week into the weekend, and southern Baja California later this weekend. These swells are likely to cause large and powerful surf and life- threatening rip current conditions. Please consult products from your local weather office.

Fresh to strong winds and rough seas over the outer periphery of Trudy dominate the outer offshore waters to the southwest of Guatemala. Scattered to numerous showers and thunderstorms also prevail across these outer waters S of 14.5N and W of 90W. Gentle to moderate winds, and moderate seas in SW swell prevail over the remainder of the offshore waters. Scattered moderate convection continues across and S of the waters of Costa Rica, Panama and Colombia E of 85W. For the forecast, fresh to strong winds and rough seas occurring S of 13N, and associated with Tropical Storm Trudy well offshore of Guatemala, will diminish through Wed as Trudy moves further from the area. Otherwise, a weak pressure gradient will support moderate or lighter winds, and moderate seas dominated by SW swell across much of the forecast waters through the end of the week. Scattered showers and thunderstorms are expected to remain active across the waters E of 85W tonight. ...REMAINDER OF THE AREA... Moderate to fresh N to NE winds and rough seas cover the waters N of 18N and west of 115W.
