Offshore of Central America (Invest EP92): Showers and thunderstorms associated with a broad area of 1006 mb low pressure continue offshore of Central America near 10.5N87.5W. Associated winds are currently 20 to 30 kt with seas of 8-11 ft. Associated convection is embedded within a very large area of concentrated convection within 600 nm of Mexico and Central America as described above. Environmental conditions are conducive for further development of this system, and a tropical depression is likely to form during the next day or two while the system moves slowly northward toward the coast of Central America. Interests along the Pacific coasts of northwestern Costa Rica, Nicaragua, Honduras, and El Salvador should monitor the progress of this system. Regardless of development, heavy rainfall and life-threatening flash flooding are possible across portions of Costa Rica, Nicaragua, El Salvador, and Guatemala through early this week. Currently, this system has a high chance of tropical cyclone formation in the next 48 hours days. Refer to the latest NHC Tropical Weather Outlook at www.hurricanes.gov for updates. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A monsoon trough extends from 10N86W to low pressure, Invest EP92, near 10.5N87.5W to 14N94W, then resumes SW of Tropical Depression 10-E near 11N106W to 08N119W to 09N130W. Numerous moderate isolated to scattered strong within 540 nm of shore between 77W and 106W. Scattered moderate isolated strong convection is noted from 07N to 12N between 106W and 111W. ...OFFSHORE WATERS WITHIN 250 NM OF MEXICO... A broad ridge extends from a 1032 mb high northeast of the Hawaiian Islands near 34N149W southeastward to west of the Revillagigedo Islands. Broad low pressure extends from southern California south-southwestward across the Baja Norte waters. This pattern is producing gentle NW winds with 6 to 7 ft seas in mixed NW and SW swell across the Baja California waters to the Revillagigedo Islands. Moderate N winds and seas 7 to 9 ft in N swell prevail across the outer waters of Baja Norte, generally N trough W of Isla Guadalupe. Fresh to locally strong NW to W winds with locally higher seas are present near the coast south of Cabo San Lucas. Tropical Depression TWO-E is offshore of Acapulco, located near 15.7N99.7W aT 2100 UTC, moving NE at 3 kt, and remains embedded within a broad and larger cyclonic circulation offshore of southern Mexico. This system is producing fresh to strong SW to W monsoonal winds with 8 to 12 ft seas in large SW swell across the outer offshore waters S through SE of TWO-E. Also part of this broad cyclonic circulation, moderate to fresh NW winds extend from near Cabo Corrientes to the western flanks of TWO-E. The entire area E of 104W and Michoacan is dominated by numerous bands of heavy showers and thunderstorms. For the forecast, Tropical Depression Two-E will strengthen to a tropical storm near 16.0N 99.1W Mon morning, move inland to 16.8N 99.5W Mon evening, move inland and weaken to a tropical depression near 17.8N 100.4W Tue morning, and dissipate Tue evening. Large cross- equatorial SW swell will move into the regional waters tonight through Mon and combine with rough wind driven seas from the tropical storm to produce dangerous marine conditions across the waters of Guerrero. Elsewhere, a broad surface ridge will sustain gentle to moderate NW winds across the Baja Norte waters through Mon evening, and across the Baja Sur to Revillagigedo Islands through Tue evening before weakening. Moderate to fresh NW to N winds and moderate to rough seas will prevail across the far outer waters of Baja Norte through early Wed. Large, cross equatorial S-SW swell will merge across the southwestern Mexico waters late tonight through Tue, and across the Baja waters Mon through Tue night. ....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Clusters of scattered to numerous showers and thunderstorms prevail across most of the near and offshore waters of Central America and southeast Mexico, and are associated with an active monsoon trough, and a developing area of low pressure near 10.5N87.5W. Please, see the Special Features section for more details. A weak surface pressure pattern continues N of the region, which is allow the eastern Pacific monsoonal circulation to dominate the region. Recent satellite data indicates that a weak low pressure center has develop along the monsoon trough near 88.5W, while the monsoon trough has lifted to near 11N-12N. Fresh to locally strong SW to W winds prevail across most of the area south of the trough and to the W of Costa Rica. Gentle to moderate winds are generally N of the trough. Seas of 7 to 10 ft in SW swell dominate the offshore waters of Central America W of 84W, and are 5 to 7 ft E of 84W. New cross-equatorial SW swell has begun to reach the waters between Ecuador and the Galapagos Islands, producing seas of 7 to 10 ft. For the forecast, new large SW swell will surge across the Central America offshore waters today through early Tue. As a result, moderate seas will quickly become rough by this evening, and then very rough by Mon morning, building to around 11 ft between Ecuador and the Galapagos. At the same time, convergent monsoonal winds will generate periods of heavy showers and strong thunderstorms across the regional offshore waters at least into early next week. Low pressure south of El Salvador will gradually strengthen the monsoonal SW to W winds across the offshore waters of Central America tonight through Mon night, leading to fresh to strong SW to W winds tonight, becoming strong to near- gale while expanding northward on Mon. Environmental conditions are conducive for further development of this system, and a tropical depression is likely to form during the next day or two while the system moves slowly northward toward the coast of Central America. Interests along the Pacific coasts of northwestern Costa Rica, Nicaragua, Honduras, and El Salvador should monitor the progress of this system. ...REMAINDER OF THE AREA... Please see the Special Features section for information on Post- Tropical Cyclone Amanda located across the Tropical Pacific W of 130W. A broad ridge extends from a 1032 mb high northeast of the Hawaiian Islands near 34N149W southeastward to west of the Revillagigedo Islands. The pressure gradient south and southeast of the ridge is producing moderate to fresh NE to E winds with 6 to 8 ft seas across the waters north of 12N and W of 130W, except seas are reaching to 10 ft near Amanda. Moderate to fresh N to NE winds and seas of 8 to 10 ft are found north of 23N between 120W and 130W. Mainly gentle winds with seas at 6 to 9 ft in mixed N and S swell prevail across the remaining waters north of the monsoon trough and east of 130W. South of the monsoon trough and west of 115W, gentle to moderate SE to SW winds and 7 to 10 ft seas in large S-SW swell prevail. Fresh to strong SW to W monsoonal winds and 9 to 14 ft seas in new SW swell are moving into the waters south of the monsoon trough to beyond the Equator and east of 115W. Gentle to moderate SE winds and seas of 9 to 12 ft in SW swell prevail the rest of the waters south of the Equator. For the forecast, the aforementioned high pressure will meander about and weaken slightly across the area through Tue as the remnant low of Amanda tracks southwestward over the western portion of the area, resulting in gradually diminishing winds across the trade wind zone. Large S to SW has crossed the equator this morning and will continue northward through the regional waters through early next week, reaching to 20N tonight through Mon. Northerly swell in the north-central waters will produce seas of 7 to 10 ft for the next several days. Fresh to strong monsoonal SW to W winds should gradually shift northward tonight through Mon evening. Seas S of 20N and E of 120W will peak at 10 to 13 ft seas tonight through Mon night before gradually subsiding Tue through Wed.
