The NWS reports that thunderstorms are moving rapidly through the area, bringing with them brief but intense rainfall and frequent lightning. Doppler radar and automated rain gauges indicated rainfall between 0.1 and 0.5 inches had already fallen by 7:41 PM, with an additional 0.5 to 0.8 inches expected before the storms pass. The heavy rainfall is expected to cause minor flooding in low-lying and poorly drained areas.

The advisory covers a broad area across northwest and west-central Washington, affecting several major cities, including:
Seattle
Tacoma
Bellevue

Olympia
Port Angeles
Bremerton
Residents in these and surrounding areas are advised to remain alert for localized flooding, especially in areas prone to water accumulation, such as low-lying roads and poorly drained locations.
Safety Precautions
Flooding of roadways is a significant concern during this event. The NWS has issued a stern reminder: "Turn around, don’t drown" when encountering flooded roads. Most flood-related fatalities occur in vehicles, emphasizing the importance of avoiding water-covered roadways.
The NWS advises drivers and residents to remain vigilant, particularly in areas where flooding is ongoing or likely to begin soon. In addition to driving safety, residents should avoid walking or wading through flooded areas and seek higher ground if necessary.
