Redondo Beach, WA
CATEGORY 2
WHAT
Based on the available data, there is no significant risk of flooding on this day. While tides reach roughly 19.3 ft in the afternoon (around 16:42), the barometric pressure is not especially low (about 1002.5 hPa), and NOAA reports a 0% flood likelihood.
WHEN
Highest tide levels occur near mid-afternoon (16:00–17:00), though flooding is not expected at any point.
IMPACTS
No notable coastal inundation or property impacts are anticipated.
• In comparison to historical Category 3 or higher events, this day’s barometric pressure is not sufficiently low to increase flood risk, and the tide height falls below the more severe thresholds seen in past Category 4–5 events.
• NOAA’s forecast indicates low likelihood (0.0%) of tidal flooding.
CATEGORY 3
WHAT
Tide heights near 19.7 ft in the evening (around 17:18), combined with somewhat lower barometric pressure (~1000.75 hPa), place conditions “close to a flood event.” However, it remains unlikely to cause significant flood damage according to the data.
WHEN
Higher tides from late afternoon to early evening.
IMPACTS
Minor ponding or very localized flooding may occur in especially low-lying areas, but significant property damage is not expected at this time.
• Though the tide is relatively high, it is still below the more impactful 20+ ft levels seen in historical Category 4–5 events.
• The barometric pressure, while lower than Day 1, does not approach the very low readings (<992.8 hPa) strongly linked with major flooding in past data.
• NOAA’s official likelihood remains at 0.0%, indicating minimal overall threat.
CATEGORY 3
WHAT
Tide levels could peak near 19.8–19.9 ft during mid-to-late afternoon/evening hours, coupled with slightly low pressure just under 1000 hPa. These factors bring conditions close to a minor flood threshold but still indicate little chance of damage according to NOAA’s 0% likelihood outlook.
WHEN
Higher tides mid-afternoon through early evening.
IMPACTS
Similar to Day 2, minor water encroachment in vulnerable coastal spots is possible, though impactful flooding or notable property damage are unlikely.
• Historically, Category 4 events have been associated with tides exceeding 20 ft and significantly lower atmospheric pressure (<992 hPa).
• Despite moderate tide heights, the latest forecasts do not support a high flood risk, and NOAA’s flood likelihood for this date remains very low.
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.
