Redondo Beach, WA
CATEGORY 2
WHAT
No risk of coastal flooding is expected. Tides will be comparatively high (reaching near 18.3 ft by midday), but barometric pressure is well above the critical low threshold, and NOAA indicates a 0% flood likelihood.
WHEN
Highest tide around midday on 09/15.
IMPACTS
No known flooding concerns. No property damage or road closures anticipated.
• Tide height reaches roughly 18.3 ft around noon, but historical data shows significantly higher tides (20–22 ft) paired with notably lower pressure before Category 3 or above events.
• Barometric pressures remain around 1005–1022 hPa, significantly higher than the sub-993 hPa levels often seen in severe flood events.
• NOAA’s Flood Likelihood Analysis reports a 0.0% chance of flooding for the day, reinforcing the conclusion that no flooding is expected.
CATEGORY 2
WHAT
No flood risk expected despite tides peaking near 18.8 ft in the afternoon. Barometric pressures remain relatively high, and NOAA forecasts minimal flood likelihood.
WHEN
Highest tide in early to mid-afternoon on 09/16.
IMPACTS
No flooding concerns for low-lying coastal areas. No property damage anticipated.
• Although peaks are near 18.8 ft, this remains below heights observed in Category 3+ historical events.
• Mean sea-level pressure values above 1007 hPa do not indicate storm conditions.
• NOAA again estimates a 0.0% flood likelihood, reflecting little to no threat of coastal encroachment.
CATEGORY 2
WHAT
No flood threat, even though the tide could approach about 19.1 ft in the mid-afternoon. Pressures at or above 1013 hPa reduce the chance of flooding, and NOAA’s official likelihood remains 0%.
WHEN
Highest tide around mid-afternoon on 09/17.
IMPACTS
No anticipated flooding on shore or in low-lying locations.
• Tides near 19 ft are below thresholds typically seen in Category 3 or higher flood events (20+ ft).
• Barometric pressure near 1013.6 hPa is relatively high and not conducive to storm surge.
• NOAA’s forecast records no sign of flooding, consistent with local historical patterns where pressures below ~993 hPa combine with significantly higher tides for notable flood events.
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.
