Area Forecast Discussion National Weather Service Seattle WA 827 AM PDT Sat Oct 23 2021

SYNOPSIS. A front will bring some rain to Western Washington today. A strong front will move through Western Washington Sunday morning. A strong low pressure system will approach the area on Sunday and then weaken somewhat and move ashore over Vancouver Island on Monday. Periods of wet blustery weather will occur through next week as additional frontal systems move through the region.

SHORT TERM /TODAY THROUGH MONDAY/. A deep low will develop far offshore today and speed toward the Pacific Northwest. A deep low will likely bottom out around 945mb by daybreak Sunday--but the low center will still be 450 miles offshore at that point. Still, the strong associated front will bluster through Western Washington Sunday morning with windy weather for many areas. Naturally the easterly gradient favors the gaps through the mountains and the area around the Strait of Juan de Fuca--but it will be such a strong front that we have a high wind warning plus wind advisories out for many areas. The coastal waters have a storm warning, and as the low gets to about 200miles west of Destruction Island later Sunday afternoon or evening southerly storm force winds will be out over the coastal waters--and the beaches ought to be awfully windy too. This will really be something to see on satellite imagery this weekend. High surf will arrive along the coast Sunday night through Monday and as the low moves ashore over Vancouver Island the tides will be about two feet above the tide table predictions so minor tidal overflow will be possible during high tide. 19

LONG TERM /TUESDAY THROUGH FRIDAY/. A frontal system will bring another round of rain and wind on Tuesday. Another wet and windy period is possible Wednesday night into Thursday. There are hints at an atmospheric river situation with setting up during this time with increased river flooding concerns but confidence in the details is low this far out. Schneider

AVIATION. West to southwesterly flow aloft this morning and this afternoon before becoming southwesterly this evening and into Sunday. An incoming frontal system will bring more rain for the remainder of the morning and into the early afternoon before activity tapers off briefly . only to resume very early Sunday morning. Most obs, especially those east of the Sound, are reporting VFR conditions at the time of this writing. Those reporting MVFR conditions are generally confined to the Olympic Peninsula and along the coast. Will see these lower cigs travel eastward as the front and its associated rain do the same. Timing on when widespread MVFR cigs will occur still a little uncertain given slow eastward progression, but should occur during the late morning/early afternoon hours. Gradual improvement still expected later in the afternoon and evening, with skies even potentially attempting to scatter briefly. A much more significant storm system will influence the area on Sunday. Winds today S/SE 5-10kts.

KSEA . VFR ceilings will drop to MVFR by 20-22Z as widespread rain ahead of the next front moves through. Gradual improvement back to VFR this afternoon and evening. Winds S/SE 7-10kts.

18/Kovacik

MARINE. The next in a series of storm systems will affect the waters today, with most recent sfc analysis showing a cold front located offshore near the Outer Coastal Waters. South winds are picking up early this morning and expect SCA level winds for most area waters /except Puget Sound/. Inherited headlines look good and require no update for next forecast issuance. Winds will gradually subside this afternoon and evening, but swells of 11-13 feet will keep for hazardous seas through the evening for the West Entrance of the Strait and the Coastal Waters/Grays Harbor Bar.

Still expecting a very strong low pressure system to rapidly deepen tonight and into Sunday over the open Pacific Waters, well outside the outer coastal zones. Nevertheless, strong winds are likely, with storm warning thresholds expected to be met for the Coastal Waters with sustained winds in the 40-50kts range. Easterly winds will pick up through the morning Sunday, with gales likely over most of the interior waters. A strong easterly push down the Strait is likely to result in Storm Warning level winds around the West Entrance.

By Sunday night, large swells are expected over the Coastal Waters, with seas building to between 25 and 30 feet. This will result in High Surf conditions and a headline for this will need to be issued in the next 12-24 hours. Expect dangerous beach conditions along the Coast through much of Sunday and Monday.

All in all, this is looking increasingly likely to be a longer duration event, with winds continuing through Monday along with high seas. Gales are likely to persist over the interior waters for Monday, with storm warning winds also likely subsiding to gale. Winds and seas will gradually subside through Tuesday but it is very possible hazardous marine conditions may continue into Tuesday morning. Yet another front around Thursday could bring another round of wind headlines along with large swells, though nothing to the extent of Sunday/Monday.

Kovacik/18

HYDROLOGY. As we head into a rather active weather pattern, flooding will become possible on the Skokomish River by about Tuesday. River flooding is not currently forecast for other area rivers. 19
