Atmospheric River Season in Washington: Keep Water Out Before the Next Storm

Western Washington’s wet season doesn’t just bring “rain”—it can bring long-duration, heavy precipitation events that test every weak point in a property. When rainfall stacks up for days, water finds a way in through roofing, siding, crawlspaces, and overworked drainage.

Here’s a practical checklist to help customers reduce risk before the next storm system hits.

1) Start at the roofline

Small issues become big problems during sustained rain.

• Clear gutters and downspouts and confirm water is flowing freely.

• Check roof penetrations (vents, flashing, skylights) for gaps or lifted edges.

• Confirm downspouts discharge away from the foundation.

2) Control runoff at the ground level

When the soil is saturated, runoff builds quickly.

• Extend downspouts (temporary extensions help in a pinch).

• Keep swales and surface drains clear of leaves and debris.

• Store outdoor items off the ground near doors and garage thresholds.

3) Don’t forget crawlspaces and basements

These areas often show damage last—after moisture has already spread.

• Confirm crawlspace vents and access doors seal properly.

• Use a dehumidifier if humidity rises and there’s any musty odor.

• If you have a sump pump, test it and ensure the discharge line is clear.

4) If water gets in, move fast

The first 24–48 hours matter.

• Shut off power to wet areas if it’s not safe.

• Document affected areas for insurance.

• Avoid running household fans if water may be in wall cavities—professional drying targets moisture you can’t see.
