A tropical wave axis is near 89W from 03N northward to El Salvador and Nicaragua, moving W at around 15 kt. No significant deep convection is present near the wave this afternoon. A tropical wave axis has been relocated significantly to the west this afternoon, near 110W from 02N to 17N, moving W around 15 to 20 kt. No significant deep convection is present near the wave this afternoon. A tropical wave axis is near 125W from 03N to 19N, moving W at around 15 kt. Scattered moderate convection is present from 09N- 12N between 121W-128W. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The monsoon trough axis extends from 10N85W to 12N115W to 10N132W, where it becomes an ITCZ axis from 10N132W to beyond 10N140W. In addition to the convection noted above with the wave near 125W, scattered moderate and isolated strong convection is present from 13N-15W between 98W-101W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Please see the Special Features section for more details on Tropical Depression Norbert. Moderate to fresh NW winds will develop offshore of SW Mexico up through the S Gulf of California by this evening. These winds will spread northwest to the central Gulf of California and offshore of Baja California Sur Thu, then to off Baja California Norte Fri and Fri night while diminishing elsewhere. Seas should remain below 8 ft with these NW winds. Fresh to strong N to NE gap winds in the Tehuantepec region will briefly diminish Thu afternoon, then return early Fri morning. The current 8 ft peak seas will diminish some through late Thu. Winds may then increase to gale force Fri night through Sat night before diminishing on Sun and Mon. Seas should peak with this gale event near 13 ft late Fri night and Sat morning and remain at least 8 ft through at least Mon night. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and WITHIN 750 NM OF ECUADOR... Winds will be light to gentle north of the monsoon trough laying along 09N, except for moderate to fresh NE to E winds in the Papagayo region Sat night. Gentle to moderate S to SW winds are expected south of the monsoon trough for the next few days becoming fresh on Mon. Mainly moderate - 5 to 7 ft - long-period S swell will prevail across the waters through at least Mon. Scattered showers and thunderstorms will be common in the Central American zones due to the proximity of the monsoon trough for at least the next couple of days. REMAINDER OF THE AREA... A moderate pressure gradient due to a 1033 mb high near 43N131W and low pressure from the ITCZ is producing generally moderate to fresh E trades. Troughing to develop west of Baja California should weaken these trades slightly Fri through Sun. A set of northerly swell continues to reach the area N of 26N, with seas ranging between 6 and 8 ft. This swell will continue to propagate across the northern waters through the next couple of days mainly between 124W and 140W. A reinforcing set of northerly swell will move across the northern waters by the end of the week into the weekend. Moderate to locally fresh monsoonal flow is noted across the remainder of the area S of the monsoon trough, with moderate to locally fresh trades N of the monsoon trough and W of 120W. Seas of 5 to 7 ft in mixed swell dominates the remainder of the waters. $$ Landsea
