Redondo Beach, WA
CATEGORY 2
WHAT
No risk of flooding is anticipated on November 22. Despite a relatively high tide near 19.76 ft early in the morning (around 07:06 AM), barometric pressure (about 1006.9 hPa) is not low enough to suggest significant flood potential, and winds are light (generally SSE around 5–9 mph).
WHEN
Highest tide around 07:00–07:15 AM PST.
IMPACTS
No notable flooding impacts expected. Normal wave action and minor tidal run-up along the shoreline are possible, but property damage or inundation of low-lying areas is unlikely.
• Historical Comparison: Previous Category 3 events, such as December 27, 2023 (17.46 ft tide, 1006.1 hPa), had higher NOAA flood likelihood scores. In contrast, NOAA currently indicates only a 0.1% chance of flooding for November 22.
• Barometric Pressure: At ~1006.9 hPa, it is well above the critical low pressures (<992.8 hPa) observed in more severe historical events.
• Wind and Direction: Light winds from the SSE do not significantly increase onshore surge.
• Conclusion: Conditions will remain safely below thresholds associated with coastal flooding.
CATEGORY 2
WHAT
No risk of flooding is forecast on November 23. Tides may briefly approach 19.75 ft in the morning (near 07:42 AM), but barometric pressure remains relatively high (about 1018.6 hPa), and NOAA’s flood likelihood is minimal.
WHEN
Highest tide around 07:30–07:50 AM PST.
IMPACTS
No flooding concerns. Coastal areas should experience normal tidal fluctuations with little chance of inundation or property impacts.
• Comparisons to Past Events: The tide height is below those historically associated with Category 4 or 5 events (often exceeding 20 ft when paired with low pressure near or below 992 hPa).
• NOAA Likelihood: Official guidance shows only a 0.1% flooding probability.
• Wind Considerations: Light southerly flow around 10–15 mph is not expected to amplify water levels.
CATEGORY 2
WHAT
Again, no risk of flooding is indicated for November 24. Although the morning high tide approaches 19.70 ft around 08:24 AM, the barometric pressure of roughly 1025.6 hPa is quite high, further reducing any flood threat.
WHEN
Highest tide near 08:15–08:30 AM PST.
IMPACTS
No notable coastal flooding impacts. Locations along the waterline may see routine tidal fluctuations, but no inundation is expected.
• Pressure Influence: A high barometric reading over 1020 hPa typically correlates with calmer marine conditions, reducing flood risk.
• Historical Context: Severe historical floods (e.g., Category 5 event on 12/27/2022) involved both very high tides (over 22 ft) and exceptionally low pressure (~978.4 hPa). Today’s conditions do not align with those.
• NOAA’s Flood Likelihood: Still at 0.1%, consistent with no impact.
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.
