NWS Forecaster Discussion
637 fxpq60 pgum 072143 afdpq Area forecast discussion National Weather Service tiyan GU 743 am chst sun Nov 8 2009 Synopsis... pgua WSR-88D shows just a few showers within the marianas waters. Satellite and model data show little change in the dry weather trend over the next few days. Tropical storm 25w is far to the east-northeast and moving farther away from the marianas. && Discussion... models continue to paint a dry picture through at least Tuesday. Radar and satellite offer little in the way of argument. In fact...the European model (ecmwf)-hires extends this dryness into Thursday. Current package handles this well so just tweaked the swells to fit the latest wave watch 3 guidance and extended the marine grids an extra 12 hours. Of some note is that we are now almost 2 inches behind on normal rainfall for November. This definitely places the Burden for catchup on the second half of the month. && Eastern micronesia... little change from the previous update. Light trade winds and a quiet weather pattern will dominate through midweek. Then...model guidance suggests that another weak trade-wind surge will nose into the region. Surf will remain above advisory thresholds for Pohnpei and Kosrae through at least tonight. && Western micronesia... convergence near the tail-end of a trough draped over western micronesia is largely responsible for cloudiness and scattered showers near Yap and Koror this morning. Believe that this feature will continue to waver over the region over the next several days...enhancing shower activity. Continued with isolated shower coverage though given the low confidence in shower placement and timing. Weather appears to remain quiet at Chuuk until above mentioned trade-wind surge moves into region late week. High surf advisory for Koror...Yap and Chuuk remains in place through tonight into Monday. && Gum watches/warnings/advisories... GU...high surf advisory until noon chst today for guz001>004. Marianas waters...none. && $$ Stanko/Lee
