Redondo Beach, WA
CATEGORY 3
WHAT
Close to a flood event but unlikely to cause major damage. Some minor coastal flooding is possible along low-lying areas.
WHEN
Highest concern is around the morning high tide at approximately 06:42 AM PST.
IMPACTS
Minor flooding of roads and nearshore properties is possible, especially in low-lying neighborhoods. No significant property damage is expected.
• Tide height is forecast to peak near 20.21 ft with a relatively low barometric pressure (~998 hPa).
• Wind speeds are predicted to be light (generally under 10 mph), reducing additional storm surge risk.
• Compared with historical Category 3 events, the tide is higher but the overall NOAA Flood Likelihood remains very low (0.7%), indicating only minor localized impacts.
CATEGORY 4
WHAT
Flooding is likely during the primary high tide period, though major property damage is not anticipated.
WHEN
Elevated risk near both the morning high tide around 07:06 AM PST and the evening high tide near 07:54 PM PST.
IMPACTS
• Possible flooding of low-lying coastal roads, small harbors, and marinas.
• Some property adjacent to the shoreline may experience minor inundation.
• Coastal parks or walkways may be temporarily impacted.
• Tide heights approach 20 ft, and barometric pressure is notably low (around 995 hPa), which increases the flood potential despite moderate wind speeds.
• Historically, Category 4 events have occurred with similar or slightly higher tides combined with low pressure. This data aligns closer to those conditions than to less severe Category 3 events.
• NOAA’s Flood Likelihood remains low in percentage terms (1.0%), but the reduced barometric pressure suggests caution.
CATEGORY 2
WHAT
No substantive flood risk is expected. Tides are high but accompanied by relatively moderate barometric pressure, resulting in minimal concern for flooding.
WHEN
Morning high tide around 07:36 AM PST does not pose a significant risk; afternoon tide near 04:12 PM PST also remains unlikely to cause flooding.
IMPACTS
No noticeable flooding impacts are expected in most areas. Routine caution along shorelines is advised, but significant inundation is not forecast.
• Although tide heights may approach 20 ft, barometric pressure near 1001 hPa and NOAA’s low flood likelihood (0.2%) indicate conditions are insufficient for significant coastal flooding.
• Compared with historical Category 3 or higher events, the barometric pressure and official NOAA Flood Likelihood percentages are notably less concerning.
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.
