Redondo Beach, WA
CATEGORY 2
WHAT
No risk of flooding is expected on January 20. Despite a relatively high tide approaching 20 ft in the early morning and late afternoon, the barometric pressure is significantly higher than the historical low-pressure flood events (1032–1034 hPa versus under 1002 hPa in past severe cases). NOAA’s flood likelihood rating is only 2.0%, indicating minimal flood potential.
WHEN
• Morning high tide around 06:48 PST
• Evening high tide around 17:06 PST
IMPACTS
No significant impacts anticipated. Low-lying areas in direct contact with tidal waters may notice typical high tide conditions but are not expected to experience flooding.
Compared to historical flooding events that involved lower barometric pressures (below ~1002 hPa) and higher NOAA flood likelihoods (over 8–10%), the current combination of high pressure and single-digit likelihood percent suggests no credible flood threat. The tide level is considerable, but the very high atmospheric pressure and calm winds diminish the overall risk.
CATEGORY 2
WHAT
No risk of flooding anticipated on January 21. Forecasted tides top out around 20 ft, but barometric pressure remains near 1028–1031 hPa, well above thresholds typically associated with flooding. NOAA places the flood likelihood at 4.0%, which remains in the low-risk range.
WHEN
• Early morning high tide around 02:06 PST
• Late afternoon/evening high tide around 17:54 PST
IMPACTS
Normal coastal conditions are expected without flooding. Localized ponding is unlikely, and no closures or damage are anticipated.
Past moderate- to high-category flood events (Category 3 or 4) tended to have either significantly lower pressure or higher NOAA flood likelihood percentages (often over 8–10%). Here, the stable, higher pressure system exerts a downward influence on sea levels, limiting water rise despite elevated tides.
CATEGORY 2
WHAT
No risk of flooding for January 22. While tides again may exceed 20 ft, the barometric pressure around 1023–1024 hPa is still much higher than in severe flood scenarios. NOAA’s flood likelihood is 4.9%, classified as low.
WHEN
• Morning high tide around 07:36 PST
• Evening high tide around 18:48 PST
IMPACTS
No notable flood impacts expected. Coastal areas should only see typical high tide levels with minimal or no inundation.
Compared with historical significant flood events (e.g., Category 5 on 12/27/2022 with a very low pressure under 980 hPa and higher tide over 22 ft), these conditions are considerably more stable. The moderate wind speeds and direction do not suggest onshore gale force, further reducing flood 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, major property damage is uncertain.
• Category 5: Likely to flood and cause property damage.
• Categories 6-7: Extremely high risk of flooding and property damage.
