Redondo Beach, WA
CATEGORY 1
WHAT
No coastal flooding is expected. Tide heights are moderate (peaking around 10–11 ft) with higher barometric pressures around 1009–1010 hPa.
WHEN
Highest tide near mid/late afternoon to early evening (around 15:00 and 18:24 local times).
IMPACTS
No significant impacts anticipated. Typical splash-over or minor ponding in very low-lying areas is unlikely to reach flood levels.
• Barometric pressure is forecast well above the critical low-pressure thresholds.
• Tide levels are comparable to or slightly higher than past Category 1 historical events (e.g., 03/02/2024 had a similar tide height around 10.4 ft but a lower pressure of ~992 hPa).
• NOAA’s Flood Likelihood for 2025-03-22 is 0.0%, indicating minimal concern.
CATEGORY 3
WHAT
Close to a flood event and worth monitoring, especially near the early morning (around 01:24) when tides reach approximately 17.8 ft. However, widespread or damaging flooding is unlikely.
WHEN
Potential peak flood risk could occur from late night into mid-morning (highest tides near 01:24 and 10:12).
IMPACTS
Minor water encroachment into very low-lying portions of the shoreline is possible, especially if onshore winds briefly push water inland. Property damage is not expected.
• The early-morning high tide (17.7–17.8 ft) is higher than typical Category 1–2 thresholds but comparable to historical Category 3 events (e.g., 12/27/2023 with tide ~17.46 ft).
• Barometric pressure hovers around 1004–993 hPa during high tides. Although lower pressure can raise concern, NOAA’s Flood Likelihood remains 0.0%.
• Winds are mostly from the south/southwest, which tend to have a smaller onshore push than west/northwest winds in this region.
CATEGORY 3
WHAT
Another above-normal tide cycle overnight. Tides could reach around 18.0 ft early in the morning; this warrants monitoring but does not strongly indicate damaging flooding.
WHEN
Highest tidal period near 01:30 and again around midday (11:42), though pressures remain moderate (~1006 hPa).
IMPACTS
Limited minor flooding possibilities along very low-lying or unprotected shore areas. Property damage is unlikely.
• Tide heights around 18.0 ft are lower than the more severe Category 4–5 thresholds historically linked with 19–22 ft tides and significantly lower barometric pressures.
• NOAA’s 0.0% Flood Likelihood for 2025-03-24 supports minimal flood concerns.
• Wind speeds remain moderate and mostly southerly, reducing the typical onshore surge risk.
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.
