Redondo Beach, WA
CATEGORY 3
WHAT
Minor coastal flooding is possible. Potential inundation of low-lying areas near shorelines and tidal waterways.
WHEN
From approximately 6:00 AM to 8:00 AM PST.
IMPACTS
Minor flooding of low-lying areas such as beaches, parks, and coastal roads. Isolated road closures are unlikely but possible.
Barometric Pressure: The barometric pressure is around 1022.8 hPa, which is significantly higher than pressures observed during historical severe flood events. This suggests stable atmospheric conditions and less severe weather.
Tide Height: A high tide of approximately 20.518 ft is expected around 7:24 AM. This tide height is higher than the historical Category 3 event (17.460 ft) but lower than the Category 4 and 5 events, indicating a moderate risk.
Wind: Wind speeds are low, around 4 km/h (2 mph), with a wind direction of East-Southeast (118 degrees). Such low wind speeds and this direction are not expected to significantly contribute to coastal flooding.
NOAA Flood Likelihood: NOAA indicates a flood likelihood of 5.8% with a distance to threshold of -0.73 m. This likelihood is comparable to the sample Category 3 event and lower than historical Category 4 events.
Based on these factors, the flood risk is close to an event worth monitoring but is unlikely to cause significant flood damage.
CATEGORY 4
WHAT
Moderate coastal flooding is likely. Potential inundation of low-lying areas near shorelines, tidal waterways, and some minor roads.
WHEN
From approximately 7:00 AM to 9:00 AM PST.
IMPACTS
Flooding of low-lying areas, parks, and coastal roads is likely. Some road closures are possible. Minor property damage may occur in vulnerable areas.
Barometric Pressure: The barometric pressure is around 1023.6 hPa, remaining high and indicating stable atmospheric conditions, which is higher than in historical severe flooding events.
Tide Height: A high tide of approximately 20.629 ft is expected around 8:00 AM, higher than Day 1 and approaching levels seen in historical Category 4 events.
Wind: Wind speeds are low to moderate, around 9-10 km/h (5-6 mph), with a wind direction from the North-Northeast (16-21 degrees). These wind conditions are not significantly contributing to increased flood risk.
NOAA Flood Likelihood: NOAA indicates a flood likelihood of 11.2% with a distance to threshold of -0.53 m. This likelihood is higher than Day 1 and comparable to historical Category 4 events.
Considering these factors, flooding is likely but is not expected to cause major property damage.
CATEGORY 4
WHAT
Moderate coastal flooding is likely. Potential inundation of low-lying areas near shorelines and tidal waterways.
WHEN
From approximately 7:30 AM to 9:30 AM PST.
IMPACTS
Flooding of low-lying areas, parks, and coastal roads is likely. Some road closures are possible. Minor property damage may occur in vulnerable areas.
Barometric Pressure: The barometric pressure is around 1028.7 hPa, which is higher than previous days and indicates stable atmospheric conditions, reducing severe weather concerns.
Tide Height: A high tide of approximately 20.712 ft is expected around 8:30 AM, the highest in the three-day period and comparable to historical Category 4 events.
Wind: Wind speeds are low to moderate, around 5-6 km/h (3-4 mph), with wind direction from the South-Southeast to Southeast (140-154 degrees). These wind conditions are not expected to significantly exacerbate flooding.
NOAA Flood Likelihood: NOAA indicates a flood likelihood of 10.8% with a distance to threshold of -0.55 m, similar to Day 2 and consistent with Category 4 events in historical data.
Despite the high barometric pressure suggesting stable weather conditions, the combination of high tide heights and NOAA's elevated flood likelihood indicates that flooding is likely but not expected to cause major property damage.
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.
