Washington Weather Alert: What You Need to Know Before Memorial Day Travel Turns into a Nightmare

Planning to get out and enjoy the long weekend in Seattle? Whether you’re thinking picnic, beach day, or a laid-back backyard barbecue, here’s a heads-up you’ll want to hear. There’s a Washington Weather Alert in effect—not because of any dangerous storms, but because traffic is expected to be a major headache.

The good news? The weather looks like it’s on your side.

A Pretty Perfect Weekend (With Just a Small Chance of Rain)

The forecast for Seattle is looking kind and cooperative. Sunday, May 25, is shaping up to be one of those easygoing days—partly sunny skies, temperatures right around 71°F, and nothing that should get in the way of outdoor plans. Whether you’re heading to a local park, the waterfront, or just soaking up some sun in your backyard, Sunday’s your day.

Memorial Day Monday will follow suit for the most part. There’s a slight chance of a shower or two, but don’t let that scare you away. The day is expected to stay mostly dry, with highs near 68°F. If you’re attending a ceremony, hosting a gathering, or simply want to be outside, you should be just fine—maybe just toss an umbrella in the car for peace of mind.

Washington Weather Alert: Roads Will Be Jammed—Plan Ahead

Now, here’s where the Washington Weather Alert really kicks in. The weather might be calm, but the traffic definitely won’t be. Memorial Day weekend is one of the busiest travel periods of the year, and this one’s no exception. If you’re heading out on I-5, expect things to slow down fast.

Here’s what the traffic pattern is looking like:

• Sunday: Southbound I-5 will likely get crowded late morning through early afternoon (10 a.m. to 3 p.m.). Northbound traffic will build later in the day, with backups expected from around 1 p.m. to 8 p.m.

• Monday: Heading back? Be ready. Southbound lanes could get sticky between 11 a.m. and 2 p.m., while northbound traffic might stay heavy from morning well into the evening—expect the worst between 10 a.m. and 9 p.m.

If your weekend involves road trips, beach drives, or backyard meetups across town, try to hit the road early—or wait until later in the evening when things ease up. A little flexibility can save you a whole lot of frustration.

Travel Tips to Keep You Moving (and Sane)

Want to skip the stress and enjoy your weekend from start to finish? Here are a few simple but smart ways to do it:

• Avoid Peak Travel Times: Leaving early or late can help you miss the worst of the traffic.

• Use Real-Time Tools: WSDOT has a great app and website with live updates, traffic cameras, and alerts. Check it before you go.

• Be Road-Ready: Make sure your car is in good shape. And don’t forget snacks, water, and a full phone battery—especially if you’re bringing kids along.

• Drive Safely: More cars on the road means more chances for things to go wrong. Keep your cool, watch your speed, and stay alert.

This Washington Weather Alert isn’t about storms—it’s about staying smart. Seattle’s weather is cooperating, which is something to celebrate. But the roads? That’s another story. With a bit of planning and some patience, you can steer clear of the worst delays and make the most of your Memorial Day weekend.
