Redondo Beach, WA
CATEGORY 2
WHAT
No significant risk of flooding is expected. Despite moderately high tides reaching around 19.3 feet, the barometric pressure is forecasted to be well above 992.8 hPa (around 1027 hPa), which greatly reduces the likelihood of coastal flooding. NOAA’s flood likelihood for this day is effectively 0%.
WHEN
The highest tides will occur early in the morning (around 04:30–05:00 AM PST) and again midday (around 01:00–01:30 PM PST).
IMPACTS
No flood-related impacts are anticipated. Shoreline and low-lying areas should remain clear of water intrusion.
Historical data shows that flooding generally occurs when tides exceed ~20 ft and barometric pressure is much lower (under ~1000 hPa). Since Day 1’s pressures remain high, and NOAA’s flood likelihood is negligible, conditions do not align with any historical flood events in the moderate or higher categories.
CATEGORY 2
WHAT
Again, no notable risk of flooding is indicated. Tides will peak near 19.7 feet but the barometric pressure (1023–1026 hPa) remains significantly above the critical low-pressure threshold. NOAA’s flood likelihood is near 0.1%.
WHEN
Higher tides occur pre-dawn (around 05:00–05:30 AM PST) and early evening (around 06:30–07:30 PM PST).
IMPACTS
Coastal areas should largely remain unaffected due to continued high atmospheric pressure and only light winds.
Comparisons to past moderate flood events (Category 3–4) reveal lower barometric pressures (often below 1010 hPa) combined with tide heights over ~20 ft. Neither condition is satisfied on Day 2, indicating minimal flood potential.
CATEGORY 2
WHAT
No significant flood risk despite tides approaching about 19.9 feet. Barometric pressure (around 1025 hPa) remains substantially high, and NOAA projects only a 0.4% flood likelihood.
WHEN
Early-morning (05:30–06:00 AM PST) tide offers the highest levels, with a secondary peak in mid-afternoon (around 02:30–03:00 PM PST).
IMPACTS
Flooding of coastal roads or properties is unlikely. Standard caution is advised near shorelines during high tide, but no inundation is expected.
While historically higher category events can occur with tides over 20 ft and significantly lower barometric pressures (e.g., Category 5 on 12/27/2022 at 22.3 ft and ~978 hPa), current Day 3 parameters align with safe conditions.
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.
