Redondo Beach, WA
CATEGORY 3
WHAT
Moderate high tides reaching close to 19–20 ft late in the evening, with barometric pressures near 1003–1005 hPa. Conditions are worth monitoring but are unlikely to cause significant flooding or notable property damage at this time.
WHEN
Greatest concern near the late-evening high tide around 23:18 PDT.
IMPACTS
Minor flooding in very low-lying coastal areas or along exposed shorelines is possible. Roads adjacent to the shoreline may have standing water. Most infrastructure is unlikely to be affected.
• Compared with historical events, the tide heights here approach levels seen in past Category 3 events (e.g., 17.460 ft on 12/27/2023 or 20.68 ft on 01/06/2025) but with moderately higher barometric pressure, reducing the severity.
• Winds are not forecast to be as strong as some Category 4 events, further lowering the flood potential.
CATEGORY 3
WHAT
Evening high tide near 19–20 ft with a barometric pressure around 1001–1002 hPa suggests a continued need for caution. While the pressure is somewhat lower than Day 1, it is still not near severe thresholds.
WHEN
Peak flood potential near 23:54 PDT during the highest tide of the day.
IMPACTS
Low-lying coastal roads and parking areas could experience ponding. No major threat to structures is expected.
• Historically, tides near 20 ft with pressures above ~995 hPa have not typically led to significant coastal flooding.
• Wind speeds are expected to remain modest, minimizing additional surge risk.
CATEGORY 3
WHAT
A midday high tide near 17 ft coincides with lower barometric pressure (~998–999 hPa). Flood potential warrants monitoring but is still unlikely to become severe.
WHEN
Highest concern near 14:24 PDT.
IMPACTS
Localized minor flooding or very shallow inundation in areas directly abutting the shoreline. Widespread property damage is not expected.
• Although barometric pressure is somewhat lower than the previous two days, the tide height of around 17 ft is notably below the more impactful 20+ ft historically associated with higher-category events.
• Similar tides of 17–18 ft in the historical record (e.g., 12/27/2023) aligned with pressures in a similar range have been categorized as Category 3.
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.
