RAIN: A nice day out there Monday but things will go downhill fast late tonight with a wave of consistent rain – heavy at times – starting at the coast this evening, spreading inland by midnight and lasting into Tuesday morning. Rainfall amounts of over a half-inch overnight, combined with clogged storm drains means there will likely be some urban/street flooding for the Tuesday morning commute.
It will also be getting increasingly windy with Wind Advisories in effect for most locations – including Puget Sound – for Tuesday.
WIND: Winds will peak at the coast in the morning and around the interior of Western Washington from late morning through the afternoon, subsiding around nightfall. Wind gusts will commonly touch 30mph with 40+ mph wind gusts likely at the coast and around Whidbey Island and quite possible everywhere else. Winds of this magnitude this early in the season will probably break some twigs and branches because of the wind load of the leaves, leading to some power outages. In addition, more leaves will be stripped off trees making for a general mess with the chance for street flooding.
I rate this wind potential a little stronger than what we had over the weekend.
THUNDERSTORM POTENTIAL: In the afternoon hours, while it’s still breezy, the precipitation will be in the form of scattered downpours as compared to the large area of general rainfall expected overnight. With these downpours during the day, we could get small hail and even lightning.
