Tropical Weather Discussion
000 axpz20 knhc 060304 twdepTropical weather discussion NWS National Hurricane Center Miami FL 0405 UTC Fri Dec 06 2013Tropical 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 0000 UTC surface analysis and satellite imagery through 0300 UTC....Intertropical convergence zone/monsoon trough...the monsoon trough extends from 09n83w to 09n92w to 06n100w where low level winds suggest a transition to ITCZ which extends to 10n113w to 10n130w to beyond 09n140w. Scattered moderate isolated strong convection was noted within 30 nm of the ITCZ between 113w and 118w....Discussion...High pressure of 1031 mb is centered N of the area near 38n137w with ridge extending se to near 20n110w. The resulting pressure gradient between the high and lower pressure in the vicinity of the ITCZ is maintaining fresh to strong trades over much of the area N of 20n and W of 125w. The high pressure center will shift closer to the area over the next 48 hours. This will maintain fresh to strong trades and seas to 10 ft over the western part of the forecast area N of the ITCZ. Otherwise...relatively benign conditions will prevail over much of the forecast area the next couple of Days.Gap winds...Gulf of Tehuantepec...a cold front will move across the west part of the Gulf of Mexico through the early part of this weekend. The front will stall over the Western Bay of Campeche early this weekend as the upper trough providing support for the front lifts out. Denser air behind the front will funnel through the chivela pass into the Gulf of Tehuantepec with winds increasing to 20-25 kt by Sat afternoon. Since the push behind the front will diminish as the front stalls this is expected to be a brief event with winds over the Gulf of Tehuantepec remaining below gale force. However...with the added component of nocturnal drainage flow...winds are expected to reach near gale force during the overnight hours Sat into the early morning hours sun. Winds will diminish below 25 kt Sun afternoon.Looking ahead for the Gulf of Tehuantepec...a stronger gap wind event is likely next week with gale conditions possible by early Wed.Gulf of papagayo...winds are expected to pulse to 20 kt during the overnight and early morning hours over the next couple of days.$$ Al
