Redondo Beach, WA
CATEGORY 4
WHAT
Flooding is likely around the morning high tide based on NOAA’s high likelihood (23.7%), a projected peak tide near 20.9 ft, and moderate barometric pressure around 1018.7 hPa. Flooding is not expected to be severe enough to cause major property damage.
WHEN
Greatest risk is near the morning high tide, roughly from 6:30 AM to 8:00 AM PST.
IMPACTS
Minor coastal inundation is possible in low-lying areas and along the immediate shoreline. Road closures or standing water in prone areas may briefly disrupt travel.
• Tide heights approach 20.9 ft, comparable to certain historical Category 4 events but under the more dangerous thresholds seen in Category 5.
• Barometric pressure remains significantly above the very low values historically associated with extreme flooding (below ~992.8 hPa).
• NOAA’s flood likelihood is higher than for many past moderate flood events, reinforcing the possibility of minor inundations.
CATEGORY 3
WHAT
There is a possibility of minor coastal flooding due to a high tide near 20.7–20.8 ft. However, the risk of property damage is low, as barometric pressure (around 1023.5 hPa) remains relatively high.
WHEN
Peak risk is around the early morning high tide, mainly from 2:30 AM to 9:00 AM PST, with the most substantial tide near 8:00 AM PST.
IMPACTS
Localized ponding on roads and low-lying areas may occur. Widespread or significant property damage is unlikely.
• While NOAA indicates a high flood likelihood (20%), the higher-than-average barometric pressure will help limit more severe impacts.
• Historical Category 3 events show similarities in tide height and pressure. The forecast aligns well with those patterns, suggesting only minor, localized flooding.
CATEGORY 3
WHAT
Close-to-flood conditions continue, driven by a tide near 20.5 ft and a flood likelihood of 12.1%. Overall, impacts are expected to remain minor.
WHEN
Mainly from early morning to midday, peaking near 9:00 AM PST when the tide is near its height.
IMPACTS
Minor overwash in usual low-lying zones. Little to no damage to infrastructure is expected.
• Tides remain high but slightly below Day 1 and Day 2 peaks.
• Barometric pressure around 1022.9 hPa is still well above historically significant low-pressure levels.
• NOAA’s lower flood likelihood compared to earlier days further suggests minor impacts.
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.
