Redondo Beach, WA
CATEGORY 2
WHAT
No significant risk of flooding is anticipated. Although tides will be relatively high (approximately 19.0 ft at peak), barometric pressure remains well above the critical low threshold (roughly 1017 hPa), and NOAA’s flood likelihood assessment for this date is 0%.
WHEN
Highest tides around 07:48 AM and 05:48 PM PST.
IMPACTS
At these tide heights, minor water ponding could occur in very low-lying spots, but no substantial coastal flooding is expected.
• Comparison with historical events shows that past Category 3 and 4 events often combined higher tides (20+ ft) with notably lower barometric pressure (below ~1006 hPa).
• Current conditions do not align with those more concerning scenarios (barometric pressure is relatively high, and NOAA predicts zero flood likelihood).
• Prevailing winds at ~12 mph from the SSE are not expected to exacerbate water levels significantly.
CATEGORY 2
WHAT
Similar to Day 1, tides will again be moderately high (near 19.0 ft), but the barometric pressure is still expected to remain comfortably above the critical low threshold (about 1016 hPa), with NOAA continuing to indicate a 0% flood likelihood.
WHEN
Highest tides around 08:36 AM and 06:18 PM PST.
IMPACTS
No substantial flooding is expected. Low-lying areas along the waterfront could see minor water ponding, but conditions should not rise to damaging flood levels.
• The 19 ft tide height is higher than some past minor events; however, the corresponding pressure remains relatively high, greatly reducing flood potential.
• NOAA’s current data provides added confidence that, barring any unforeseen change, flood risk remains minimal.
CATEGORY 2
WHAT
While Day 3 sees slightly lower peak tides (around 18.7–18.9 ft), barometric pressure remains high (approximately 1018 hPa). NOAA’s forecast again indicates a 0% likelihood of flooding.
WHEN
Highest tides around 09:30 AM and 06:54 PM PST.
IMPACTS
No significant flood impacts are likely. Typical localized areas prone to minor ponding may experience shallow water, but broader coastal flooding issues are not expected.
• Historical data indicates that Category 4 and above events involve combinations of very high tides (exceeding about 20 ft) and low pressure near or below ~1002 hPa. Day 3 conditions do not approach those thresholds.
• Forecast wind directions do not suggest added onshore flow that could amplify coastal water levels.
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.
