Redondo Beach, WA
CATEGORY 3
WHAT Minor coastal flooding possible. Possible inundation of up to 1 foot above ground level near shorelines and low-lying areas.
WHEN From early morning to late afternoon, highest risk around high tides at 5:48 AM and 3:24 PM PST.
IMPACTS Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible.
The barometric pressure during the high tides on December 15 is relatively high, at 1018.89 hPa and 1020.42 hPa, indicating stable atmospheric conditions. Tide heights are expected to reach up to 20.16 feet at 5:48 AM, which is below the 21-foot threshold associated with significant flood events in historical data. Wind speeds are moderate, around 12 km/h (8 mph), coming predominantly from the south, which is less likely to contribute to coastal flooding in this area. NOAA's flood likelihood for this day is high, with a 9.5% chance and a distance to the flood threshold of -0.59 meters, suggesting tides are below the flood threshold. Comparing these conditions with historical Category 3 events, minor flooding is possible and worth monitoring, but significant damage is unlikely.

WHAT Minor coastal flooding possible. Possible inundation of up to 1 foot above ground level near shorelines and low-lying areas.
WHEN From early morning to late afternoon, highest risk around high tides at 6:36 AM and 4:12 PM PST.
IMPACTS Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible.
On December 16, the barometric pressure is forecasted to be high, at 1022.51 hPa and 1029.32 hPa during the times of high tides, indicating minimal influence from low-pressure systems that typically enhance flood risks. The maximum tide height is anticipated to be approximately 20.80 feet at 6:36 AM, still below the critical 21-foot threshold. Wind speeds are low, around 5 km/h (3 mph), from the east-northeast to south-southeast, which are not directions that typically exacerbate flooding in Redondo Beach. NOAA's flood likelihood is noted at 15.1% with a distance to the flood threshold of -0.44 meters. While this percentage is higher than the previous day, the elevated barometric pressure and moderate tide heights suggest a similar risk level to historical Category 3 events. Monitoring is advised, but significant flooding is not expected.

WHAT Minor coastal flooding possible. Possible inundation of up to 1 foot above ground level near shorelines and low-lying areas.
WHEN From early morning to early evening, highest risk around high tides at 7:18 AM and 5:00 PM PST.
IMPACTS Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible.
For December 17, the barometric pressure is forecasted to be very high, at 1032.72 hPa during both high tides, suggesting strong atmospheric stability and a lower risk of severe weather conditions that could lead to flooding. The highest tide is expected to reach about 20.77 feet at 7:18 AM, remaining below the 21-foot concern level seen in more severe historical events. Wind speeds are mild, approximately 4 km/h (2 mph), coming from east-southeast to east directions, which are not typically associated with increased flood risk in the area. NOAA reports a flood likelihood of 15.7% with a distance to the flood threshold of -0.43 meters. Although this is the highest likelihood percentage among the three days, the substantial barometric pressure and absence of other exacerbating factors align this day's conditions with previous Category 3 events, indicating that while minor flooding is possible, major impacts are not anticipated.
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.
