Redondo Beach, WA
CATEGORY 2
WHAT
No risk of coastal flooding is expected. While water levels will be fairly high in the early morning, conditions are not anticipated to produce significant inundation.
WHEN
Highest tide near 05:06 AM PST.
IMPACTS
No coastal flood impacts are expected; typical minor pooling in extremely low-lying areas near the shoreline is possible but not likely to cause issues.
Barometric pressure readings around 1024 hPa are quite high, significantly reducing flood potential despite the peak tide approaching 20.3 ft. NOAA’s flood likelihood is only 3.8%. Historically, similar tide levels with comparable or even lower barometric pressure resulted in either minor or no flooding. Therefore, Category 2 is assigned as no substantial flood risk is indicated.
CATEGORY 3
WHAT
Close to a flood event and worth monitoring. Conditions may lead to very minor inundation in the lowest-lying spots around the coastline.
WHEN
Highest concern near the early morning high tide around 05:48 AM PST. A secondary high tide occurs mid-afternoon but is lower and combined with high pressure.
IMPACTS
Flood impacts, if any, would be quite limited. Some water may briefly pool along beaches and in shoreline parking areas, but significant property damage is not expected.
Tide heights could reach about 20.7 ft. Although NOAA’s likelihood is rated “High” (16.3%), the barometric pressure remains elevated (approx. 1024 hPa), which helps counteract tidal flooding. By comparison with historical Category 3 events, these conditions appear consistent with only minor impacts.
CATEGORY 4
WHAT
Flooding is likely but is not expected to cause major property damage. Coastal areas could see moderate inundation.
WHEN
Greatest risk near 06:30 AM PST and again late afternoon near 16:24 PM PST.
IMPACTS
Portions of roadways and parking areas along the immediate shoreline may temporarily flood. While this event could prompt short-term closures in very flood-prone areas, extensive or severe damage is unlikely.
Projected tide heights may approach 20.9 ft, which is higher than many past moderate flood events, but the barometric pressure is extremely high (around 1026 hPa). NOAA’s model nonetheless indicates about a 20.6% likelihood for flooding. Comparing to previous Category 4 occurrences, these data suggest moderate flooding is probable, though not at catastrophic levels.
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.
• Categories 1-2: No risk of flooding.
• Category 3: Close to a flood event and worth monitoring.
• Category 4: Flooding is likely however, it is uncertain if this will cause major property damage.
• Category 5: Likely to flood and cause property damage.
• Categories 6-7: Extremely high risk of flooding and property damage.
