803 AXPZ20 KNHC 132046 TWDEP Tropical Weather Discussion NWS National Hurricane Center Miami FL 2011 UTC Fri Mar 13 2020 Tropical Weather Discussion for the eastern Pacific Ocean from the Equator to 32N, east of 140W. The following information is based on satellite imagery, weather observations, radar, and meteorological analysis. Based on 1800 UTC surface analysis and satellite imagery through 2030 UTC. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... A surface trough 09N85W to 02N103W. The ITCZ continues from 02N103W to 02N126W to beyond 04N140W. Scattered moderate convection is noted from 00N to 07N between 115W and 125W. OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Low pressure that was located just N off the Gulf of California has weakened and dissipated today. A surface trough located from 31N116W to 24N120W is also dissipating. Ahead of this trough, moderate to fresh S winds in the northern Gulf of California will prevail through the evening, then gradually diminish overnight. Northerly winds near 15 kt prevail across the southern Gulf and extend to Cabo Corrientes and are expected to continue through the weekend, and increase to 15-20 kt during the afternoon and evening hours each day. Elsewhere from Cabo Corrientes to Puerto Angel, tranquil marine conditions generally will prevail through the weekend. Across the Gulf of Tehuantepec, variable winds and slight seas are expected through Sat evening before northerly gap winds spill across the Gulf Sat night into Sun morning, and peaking near 30 kt. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Fresh NE to E winds will continue across the Gulf of Papagayo region into next week, with nocturnal winds pulsing to around 25 kt across much of the area. Fresh northerly winds are also forecast across the Gulf of Panama extending downstream to near 05N during this time. No large swell is anticipated during the next several days. REMAINDER OF THE AREA... North of the ITCZ, moderate to occasionally fresh NE tradewinds will prevail W of 120W and S of 17N through the weekend, with seas in the area of 6 to 8 ft in N to NW swell. Looking ahead, computer models suggest a significant low pressure system will develop offshore of California over the weekend and dive southward to near 31N by mid week, producing a significant increase in northerly swell and the potential for gale force winds associated with low pressure sweeping into the NE waters late Wed or Thu. $$ KONARIK
