Area forecast discussion National Weather Service tiyan GU 526 am chst Sat Feb 13 2016 Synopsis... a shear line to the south of Guam continues to produce fresh to strong winds across the marianas. Mostly cloudy skies and a few rainshowers remain over the region. Buoy data shows seas remaining around 10 to 11 feet. && Discussion... scattered light showers associated with the shear line to the south of Guam have pushed westward out of the marianas. Models continue to indicate the trade winds will gradually diminish over the next couple days...while mostly cloudy skies today will become partly cloudy by Sunday. Much drier conditions are expected by midweek... with shower coverage decreasing to slight chance for Monday through Tuesday. && Marine... a high surf advisory and Small Craft Advisory remain in effect over Guam and the cnmi waters. Fresh to strong winds associated with a shear line to the south of Guam will continue across the marianas coastal waters through Saturday night. Combined seas of 10 to 12 feet will continue through Sunday night...then begin to subside early Monday. Seas are expected to fall to between 6 and 8 feet by Tuesday. && Fire weather... the Fire Weather Watch remains in effect. Light showers have moved across Guam Friday...but did little to alleviate the dry conditions. Rainfall amounts were generally around one tenth of an inch or less. Winds also remain gusty and drier weather is expected in the coming days. && Eastern micronesia... a couple of trade-wind disturbances are seen across the area. One is near Pohnpei while the other is east-southeast of Majuro near the date line. Thick cirrus is seen elsewhere from Chuuk to Kosrae. Reduced short-term precipitation at Majuro based on slower westward progress of the disturbance by the date line. Models show both systems sliding westward with little northward spreading. Under this scenario...Kosrae will see more moisture later in the weekend and early next week while Chuuk...Pohnpei and Majuro see increased cloudiness and some additional rain. Unfortunately...the bulk of rain is expected to stay nearer Kosrae and southward. High surf advisories remain in effect for Chuuk...Pohnpei and Kosrae...and will likely be needed for Majuro over the weekend. Sea and wind conditions are hazardous for small craft at Chuuk and Pohnpei and will become hazardous at Kosrae and Majuro later tonight. Large northeast waves generated by strong trade winds along with a large north swell arriving across much of micronesia will cause hazardous seas and surf during the next few days. && Western micronesia... Chuuk discussion included with eastern micronesia because of similar conditions. The shear line that passes south of Guam becomes more diffuse as it nears Yap. Satellite imagery shows a broad area of low and middle-level cloudiness but not much precipitation. As high pressure well north of the marianas shifts farther east...the shear line will dissipate further and winds will gradually decrease. Drier weather is expected by early next week. High surf and small craft advisories remain in effect for Koror and Yap. Large northeast waves generated by strong trade winds along with a large north swell moving across western micronesia will cause hazardous surf and sea conditions through this weekend. && Gum watches/warnings/advisories... GU...Fire Weather Watch through this afternoon for guz001. High surf advisory until 6 PM chst Monday for guz001>004. Marianas waters...Small Craft Advisory until 6 PM chst Monday for pmz151>154. && $$ Kleeschulte/W. Aydlett
