Marine Weather and Tides
12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed.
10/9/2019 Updated the Marine Zones.
9/4/2019 Fixed the weather maps due to NOAA moving them.

SYNOPSIS. A mild and active weather pattern is expected into next week with several rounds of mainly valley rain and mountain snow.
DISCUSSION. Tonight through Friday: Our unsettled weather pattern continues today as a SW-NE oriented frontal system approaches the coast. Precipitation associated with a warm front passed through this morning, and as of this writing stratiform precipitation is moving through central and eastern Washington. Steady precipitation will increase over the next few hours, and continue tonight into Friday for portions of the region. Considerable warm air aloft has moved into the region, and the lowlands will largely see precipitation fall in the form of rain with this system. The threat for freezing rain along the east slopes of the Cascades has subsided as surface temperatures have warmed above freezing. In fact, snow levels are expected to be above 5000-6000 ft, well above major pass levels. Look for lows generally in the 30s tonight, and highs in the 40s to lower 50s Friday. As the cold front passes Friday, we may see locally breezy southwest winds develop across the Columbia Basin and into the Palouse.
Friday night through Saturday: Generally quieter weather is forecast across the region for Friday night, which may set the stage for foggy conditions across the valleys. The next in our series of weather systems looks to arrive during the day Saturday. This system won't quite have the moisture tap of prior or subsequent storm systems . expect generally light valley rain and mountain snow with that system.
Saturday night through Sunday: Our unsettled weather pattern continues as the next storm system arrives late Saturday into Sunday. This system is projected to have a better moisture tap than the Saturday system, and perhaps not unlike the current storm system. This again will be another milder storm system, with valley rain and snow levels rising to 3500-4500 ft.
Given these frequent rounds of lowland rain, we will be monitoring for potential hydrologic issues. At this time, guidance from the Northwest RFC and the National Water Model would suggest that mainstem rivers and streams will be able to handle the rainfall and minor lowland snowmelt. The primary concerns at this stage will be localized roadway and field flooding. Dang
Monday through Thursday: The same pattern continues as one upper level disturbance ejects east from the Inland Northwest as another system enters the Pac Northwest. A split upper flow setting up by Tuesday complicates the pattern with ensemble model guidance system disagreeing as to possible trajectories for applicable forcing and low to mid-level moisture transport. European guidance takes a more direct approach with moisture evenly spread across the Cascades while the GFS ensemble shows less precipitation impacts across the northern Cascades with increased POPs south into the Camas Prairie and central Idaho Panhandle drawing a winning ticket. But this pattern will settle down in preparation for the next upstream disturbance entering the region by late Wednesday into Thursday. Plenty of moisture will be provided by a well-established atmospheric river along with decent dynamics accompanying a 160-170kt North Pac Jet core. Although timing improves with each model run, ensemble and deterministic guidance differ slightly on how much moisture will inject into the region with the westerly upper flow. Although the take home message does imply that some uncertainty still follows the general model guidance, the above average temperatures and varying snow levels will keep any significant snowfall confined to higher mountain elevations with minor impacts continuing for area mountain passes. A mix of rain and snow is still possible, however, during the early morning hours across northern valley locations and the northern Idaho Panhandle. /aky
AVIATION. 00Z TAFS: A slow moving occluded front running north to south along the WA/OR coast at 00Z Friday will slowly track through the region through the next 24 hours to the ID/MT border by 00Z Saturday. A moist feed of Pacific moisture will feed widespread RA ahead of and along this front impacting most TAF sites with MVFR and IFR conditions. The KEAT and KMWH TAF sites will deteriorate to LIFR conditions in a very moist and calm boundary layer during occasional breaks in pcpn. The KLWS and KPUW TAF sites should remain MVFR during this period with southeasterly downslope flow ahead of the occlusion. /MJF

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
