Redondo Beach, WA
CATEGORY 3
WHAT Minor coastal flooding is possible. Expected inundation of up to 0.5 feet above ground level near shorelines and low-lying areas.
WHEN From 6:00 AM to 8:00 AM PST.
IMPACTS Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible.
The barometric pressure is high at 1023.7 hPa on December 16, which is significantly higher than in historical severe flood events, suggesting stable atmospheric conditions. The tide height is expected to peak at 20.8 feet around 6:36 AM, higher than the historical Category 3 event but lower than Category 4 and 5 events. Wind speeds are low, around 4 km/h (2 mph) from the northeast, minimizing additional flood risk from wind-driven water. NOAA's flood likelihood is high at 15.1%, with water levels expected to exceed the flood threshold by 0.44 meters. Despite the high tide and NOAA's forecast, the elevated barometric pressure reduces the overall flood risk to a Category 3 event.

WHAT Minor coastal flooding is possible. Inundation of up to 0.5 feet above ground level may occur near shorelines and low-lying areas.
WHEN From 6:30 AM to 8:30 AM PST.
IMPACTS Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible.
On December 17, barometric pressure remains high at approximately 1032.68 hPa, indicating stable weather conditions. The tide height is projected to reach 20.76 feet around 7:18 AM, similar to the previous day. Wind speeds are minimal, about 4 km/h (2 mph) from the east-southeast, which is less likely to contribute to flooding. NOAA's flood likelihood is high at 15.7%, with water levels expected to exceed the flood threshold by 0.43 meters. The combination of high barometric pressure and moderate tide heights suggests a Category 3 event, indicating minor flooding potential.
CATEGORY 3
WHAT Minor coastal flooding is possible. Inundation up to 0.3 feet above ground level near shorelines and low-lying areas is expected.
WHEN From 5:30 PM to 7:30 PM PST.
IMPACTS Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible.
December 18 shows a continued high barometric pressure of about 1034.52 hPa. The highest tide is expected at 5:54 PM with a height of 17.56 feet, which is comparable to the historical Category 3 event. Wind speeds may reach up to 16 km/h (10 mph) from the south-southwest in the morning but are expected to decrease by the time of high tide. NOAA's flood likelihood is high at 10%, with water levels exceeding the flood threshold by 0.57 meters. Despite the lower tide height compared to previous days, the NOAA forecast suggests monitoring conditions, resulting in a Category 3 classification.
You should monitor later forecasts and be alert for possible Flood Warnings. Those living in areas prone to flooding should be prepared to take action should flooding develop.
