Marine
Updated 230am PDT Sunday 19 September 2021...The front that brought showers and scattered thunderstorms to the marine waters last night is moving onshore. Steep west to northwest swell dominated seas are expected today behind the front. Then the thermal trough will return tonight and strengthen into Monday. Northerly winds will increase Monday into Monday evening with steep seas for most areas, except very steep seas are possible south of Port Orford. Winds could near gale force in those areas as well. We've issued a hazardous seas watch for south of Cape Blanco since seas are expected to be very steep and hazardous.

The thermal trough will weaken Tuesday. Winds and seas will be relatively light Tuesday through Tuesday night, with a very weak front brushing past to the north. The northerly wind pattern is expected to strengthen Wednesday into Thursday with gusty northerly winds and building wind driven seas that will again be strongest south of Cape Blanco. -Spilde

Fire Weather
Updated 400am PDT Sunday 19 September 2021...An upper level trough will move east out of the region today. Showers will taper off into the evening as the cold pool(a region of relatively cold air) aloft shifts east with the upper trough and an upper ridge builds in quickly from the west.

This rain will not be a "season-ending event", but the rain will make a significant dent in the season. Ridging and dry conditions will be quick to return on the backside of the system Monday. Also, there are indications of some gusty east winds, especially over the ridges and the usual downslope locations Monday into Monday night with poor RH recoveries. As a result, fire weather concerns may quickly return despite the rains. A weak front Wednesday brings cooler temperatures, but ridging builds quickly behind it and the remainder of the extended forecast remains dry with above normal temperatures.
