When Will the Rain Stop? December 2025 Storm Timeline for Vancouver WA

December 2025 Storm Timeline: What Vancouver WA Homeowners Should Expect

After two weeks of historic rainfall, Vancouver WA homeowners want to know one thing: when will the rain stop? The honest answer is not encouraging, but understanding what is coming helps you prepare.

Thursday December 18: Heaviest Day

Today brings the most significant rainfall of the week. A strong atmospheric river is delivering 2 to 3 inches across Clark County, with some areas seeing up to 4 inches by Friday morning.

Wind advisories are in effect through 7 PM with gusts reaching 45 mph in the Vancouver metro area. Combined with saturated soils, expect additional downed trees and power outages.

The Flood Watch remains in effect through late Friday night.

Friday December 19: Gradual Decrease

Rain tapers through Friday but does not stop completely. Showers continue with cooler temperatures around 47°F. Rivers remain elevated and some flooding may persist through Saturday.

This is your best opportunity for a brief outdoor assessment of your property before the next round.

Weekend December 20-21: Brief Respite

Lighter precipitation is expected Saturday and Sunday, though completely dry days are unlikely. Use any breaks to:

• Clear debris from gutters and downspouts
• Check for storm damage to your roof
• Remove fallen branches from your yard
• Inspect your foundation for water intrusion signs

Next Week December 22-24: More Rain Returns

Additional rounds of moderate to heavy precipitation are forecast for Monday and Tuesday. The persistent onshore flow pattern continues directing Pacific moisture into the region.

This means your drainage systems face another test just before Christmas. Any gutter blockages or drainage issues will create problems during the next wave.

Why the Rain Keeps Coming

An anchored weather pattern is driving seemingly endless atmospheric rivers into the Pacific Northwest. This same pattern has delivered record snowfall to the Cascades and historic flooding to lowland areas.

La Niña conditions typically bring wetter than normal winters to our region, and forecasters see no significant pattern change through late December.

Extended Outlook Through Late December

No extended dry period is forecast through the end of the month. Vancouver WA homeowners should plan for continued wet conditions and prepare their homes accordingly.

Rivers may remain elevated into late December. Areas that flooded in early December remain at risk with each new storm system.

What You Can Do Now

With more rain guaranteed, focus on what you can control:

• Ensure gutters are clear so water drains properly
• Verify downspouts direct water away from your foundation
• Clear storm drains near your property
• Check for gutter damage from recent winds
• Document any existing damage for insurance purposes

The rain will eventually stop, but not before more storms test your home's drainage systems.
