Portland woke up under low clouds on Saturday, March 14, 2026, with temperatures in the low 40s and a brisk northwest breeze. The heaviest band of the atmospheric river has shifted south, but saturated ground and high creek levels keep parts of the metro on alert for minor flooding through the afternoon. Much of the day should be drier, making for a mostly fine Saturday for errands and outdoor plans, though low-lying streets remain the top concern.
Flood Watch Through This Afternoon
The National Weather Service has a Flood Watch in effect through 5:00 PM PDT Saturday for much of the Portland metro and nearby lowlands; saturated soils and already-full streams raise the chance of urban and small‑stream flooding, according to NWS Portland. Coastal and near‑shore waters are also under Small Craft Advisories through 11 PM Saturday, with seas running around 9–10 feet and easing slowly. If you live in known flood‑prone spots, keep a close eye on local road closures and be prepared to move to higher ground if conditions change.
What To Expect Today
Saturday should trend drier after morning, with mostly sunny breaks and a high near 51°F; afternoon lows drop a degree or two later in the day. West‑northwest winds are light, generally 5–8 mph, so expect a breezy but not blustery afternoon for most neighborhoods. Showers, if they occur, will be mostly confined to higher terrain like the Coast Range and Cascades.
Rivers, Roads And Boaters
Several creeks and smaller rivers are already in action or minor flood stage and are sensitive to any extra rain; NWS hydrology notes places such as Johnson Creek near Sycamore and coastal rivers have been running high. Drivers should avoid flooded streets, never attempt to drive through standing water, and boaters should heed Small Craft Advisories for exposed coastal waters. Local public works and transportation agencies may close low spots without much notice, so plan extra time for commutes this afternoon.
Looking Ahead
Sunday brings a slightly higher chance of light rain late in the day and into the night, then a warmer pattern builds early next week with inland highs likely back into the 60s. Rain returns in earnest by Tuesday with periods of light to moderate rain through midweek, so expect a swing from this short dry break to a wetter start to the week.

If you live in a flood‑prone area, keep drainways clear of debris, avoid driving through standing water, and follow updates from local officials and NWS Portland for the latest watches and warnings.
