Redondo Beach, WA
CATEGORY 2
WHAT
No risk of flooding is expected. The tide will reach moderate levels (peaking around 18.3–18.7 ft) but is paired with an unusually high barometric pressure of approximately 1036 hPa, which significantly reduces flood potential.
WHEN
Highest tides are expected in the late afternoon (around 16:00 PST) and again in the evening (around 21:00 PST).
IMPACTS
No observed or anticipated flooding. Low-lying coastal areas should remain unaffected.
• NOAA’s Flood Likelihood for 2025-10-21 is 0%, indicating minimal concern.
• Historical Category 3 or higher flood events were associated with lower barometric pressures and higher tide heights (above roughly 19–20 ft).
• Current conditions, by contrast, feature high barometric pressure and an 18+ ft tide that remains well below the typical threshold for flooding.
CATEGORY 2
WHAT
No flooding risk is indicated. While tide heights will approach around 18.4–18.6 ft, continued very high barometric pressures (exceeding 1033 hPa) greatly reduce any potential flood threat.
WHEN
Late-night into early-morning high tides (around 05:48 PST) and an afternoon to early-evening peak tide (near 16:24 PST).
IMPACTS
No impacts expected for roads, shorelines, or low-lying areas. No disruptions anticipated.
• NOAA’s Flood Likelihood for 2025-10-22 remains at 0%.
• Comparing with a historical Category 3 event (e.g., 17.46 ft tide with ~1006 hPa pressure), we see significantly higher pressure and similar or slightly higher tides. The high pressure offsets the usual tidal risk.
CATEGORY 2
WHAT
Still no indication of flooding. Tide heights could near 18.9 ft; however, barometric pressure is forecast to remain very high (around 1034–1035 hPa), keeping the risk minimal.
WHEN
Early morning peak (approx. 06:30 PST) and late afternoon peak (around 16:48 PST).
IMPACTS
No expected roadway or property impacts in coastal zones.
• NOAA’s Flood Likelihood for 2025-10-23 is also 0%.
• Historically higher-risk flooding requires much lower barometric pressures (e.g., ~992 hPa) combined with tides above 20–21 ft. This forecast falls well outside those 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.
