The following information is based on satellite imagery, weather observations, radar and meteorological analysis. Based on 1200 UTC surface analysis and satellite imagery through 1745 UTC. ...SPECIAL FEATURES... ...Atlantic Gale Warning... Weak low pressure developing along a stalled front over the Gulf of Mexico will move NE across the NW Bahamas and NW waters Sun night then to the waters between Bermuda and the Carolinas Mon. Gales are expected to develop on either side of the front from Sun night, continuing through Mon night. Please refer to the High Seas Forecast product under AWIPS/WMO headers HSFAT2/FZNT02 KNHC for more details. ...Gulf of Mexico Gale Warning... A center of low pressure is forecast to develop along a frontal boundary in the SW gulf early on Sun. A tight pressure gradient between the low and strong high pressure building behind it will lead to the development of gale force winds. Gale force winds will affect the Bay of Campeche and the SE basin through early Mon. Please refer to the High Seas Forecast product under AWIPS/WMO headers HSFAT2/FZNT02 KNHC for more details. ...Caribbean Gale Warning... A cold front is expected to enter the northwest Caribbean on Sun night. Gale-force winds are expected W of the front, with seas up to 12 ft. These conditions will subside by early Mon morning. Please refer to the High Seas Forecast product under AWIPS/WMO headers HSFAT2/FZNT02 KNHC for more details. ...MONSOON TROUGH/ITCZ... The monsoon trough emerges from the coast of western Africa near 04N07W and extends to 02N18W to 0N29W. The ITCZ continues from that point to 01S40W to the coast of South America near 02S49W. Numerous moderate to isolated strong convection is from 01N to 05N between 03W to 09W. Scattered moderate isolated strong convection is elsewhere N of 01N E of 03W. GULF OF MEXICO... A stalled frontal boundary across the Yucatan Channel and along the NW coast of Cuba will gradually lift northward across the Straits of Florida and SE Gulf of Mexico today through early Sun. Reinforcing high pressure will force the front SE on Sun, with low pressure expected to develop along the frontal boundary in the SW Gulf, then move ENE toward Florida and the western Atlantic Mon. Gale conditions are expected in the southwest Gulf Sun morning and then will shift ENE across the central and SE portions with the low pressure through Sun night. High pressure will rebuild across the region behind the exiting low early next week. Another cold front will enter the Gulf on Tue. Refer to the Special Features section for further details. CARIBBEAN SEA... A stationary front over the Yucatan Channel will drift N into the SE Gulf of Mexico today, then sink southward across the NW Caribbean Sun night through Mon. North gales are briefly expected along the front across the Yucatan Channel Sun night. The front will move SE and stall from central Cuba to SE coast of Nicaragua Mon night and gradually dissipate Tue. NW swell prevailing over the Atlantic waters off the Leeward Islands will subside through the weekend. ATLANTIC OCEAN... A stalled front reaches from 31N69W to the Straits of Florida with a pre-frontal trough extending from 30N68W to 22N73W. Scattered moderate convection associated with these features covers the region N of 27N between 60W and 78W. Isolated showers are elsewhere from 22N to 27N, including the Bahamas. A 1008 mb low is over the central Atlc with an associated cold front extending along 30N29W to 19N29W where it starts to dissipate towards 13N44W to E of the Windward Islands near 15N59W. Scattered showers and isolated tstms associated with this low pressure system are N of 25N between 20W and 40W. Weak low pressure developing along the stalled front over the Gulf of Mexico will move NE across the NW Bahamas and NW waters Sun night then to the waters between Bermuda and the Carolinas Mon. Gales are expected to develop on either side of the front during this time. The front will start to shift southeast in the wake of the low pressure, reaching from 31N72W to E central Cuba by Mon evening, before stalling and dissipating Tue. Another cold front will move off the northeast Florida coast Tue night. For additional information please visit http://www.hurricanes.gov/marine $$ Ramos
