The following information is based on satellite imagery, weather observations, radar, and meteorological analysis. Based on 0600 UTC surface analysis and satellite imagery through 0815 UTC. ...TROPICAL WAVES... Tropical wave extends from 07N107W to 16N107W moving W at 10 to 15 kt. The wave remains within the influence of a 700 mb low centered along the wave axis near 13N and a maximum in 850 mb relative vorticity to the E of the wave near 13N106W. No significant deep convection is occurring with the wave at this time. ...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... The Monsoon Trough axis extends from 09N108W to 07N117W. The ITCZ axis extends from 07N117W to 08N125W to 07N134W to 08N140W. Widely scattered moderate convection is from 07N to 10N between 107W and 113W. ...DISCUSSION... OFFSHORE WATERS WITHIN 250 NM OF MEXICO... Relatively tranquil conditions are expected in the offshore waters of Mexico with the exception of occasional fresh NW winds expected N of 26N by Saturday night. The fresh NW winds will persist through early Tuesday. Seas will slowly build to 8 ft in NW swell and reach the offshore zones by Monday night. As winds diminish by Tuesday...seas will subside as well into a 5 to 7 ft range. In the Gulf of California...gentle to moderate southerly flow is expected N of 30N through Saturday...then fresh to locally strong SW winds are forecast N of 29.5N Saturday night into early Sunday...with seas building to about 5 ft. OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND WITHIN 750 NM OF ECUADOR... Gentle to moderate west-southwesterly winds and 4 to 6 ft seas are expected N of 08N...and moderate to fresh southerly winds with 5 to 7 ft seas forecast S of 08N through early Friday. Light to moderate southerly flow and 3 to 6 ft seas are forecast thereafter through Monday night. REMAINDER OF THE AREA... A 1019 mb high is analyzed near 25N129W with a ridge extending southeastward to near 17N114W. Gentle to locally moderate anticyclonic flow is observed S of the ridge to along 10N. Moderate SW flow is present to the N of the surface high...and also to the E of a weak cold front analyzed from near 31N131W to 26N140W. Gentle to moderate northerly flow is occurring to the NW of the front. The front will lose its upper level support as broad upper level troughing N of the area slides eastward. As a result...the front is forecast to become stationary from near 28N130W to 24N140W on Saturday and gradually become diffuse through Sunday as a stronger area of high pressure builds southeastward across the northwest and central portions of the discussion area. $$ HUFFMAN
