Rain Forecast 2/17 – 2/19

The National Weather Service hazardous weather briefing this morning: Lingering weather impacts continue today with scattered showers and a few thunderstorms. While the risk for widespread flooding has decreased, localized flooding remains a concern for areas that receive heavier rainfall today. Rain amounts will vary from place to place given the scattered nature of the showers, with most likely amounts generally 0.25-1.25″. However a few places could pick up greater amounts if a heavier shower or storm impacts them. Rain will gradually decrease from north to south late this afternoon and into tonight.

Key points:

  • Scattered showers and a few thunderstorms today.
  • Most likely rain amounts generally 0.25″ to 1.25″ – however locally higher totals possible in thunderstorms.
  • Conditional risk for localized amounts exceeding 1.5″ – but low confidence.
  • Widespread flooding concerns have lessened, but localized flooding is possible where heaver showers/storms occur.
  • Can’t rule out flash flooding if storms impact an urban area or burn scar; but low confidence in this occurring.
  • Bay Area rain chances increase late morning North Bay; afternoon into early evening elsewhere.
  • Central Coast rain chances increase late afternoon into the evening and overnight hours.
  • Only a few lingering showers for Wednesday morning.

Changes from previous briefing:

  • Risk level increased to moderate for North Bay given saturated soils and ongoing creek and stream flooding.

Forecast confidence is high that weather risk levels are Minor today and tonight. Additional rainfall: 0.25-1″ except locally higher amounts in thunderstorms. Those living in river, stream, or creek beds may be displaced by rising water. Saturated soils will not absorb additional water, causing increased runoff. Roadway, urban, and small stream flooding possible. Shallow landslides (includes loose rocks on roads) possible. Download the full briefing here.

Wednesday onward weather risk levels are forecast as Little to None.
