Redondo Beach, WA
CATEGORY 3
WHAT
Coastal waters will reach a high tide near 20.1 ft. Barometric pressure is forecast to be around 1007.9 hPa, which is not extremely low but does warrant monitoring. Overall conditions are close to a flood event, although unlikely to result in property damage.
WHEN
Highest risk near the afternoon high tide, roughly from 5:30 PM to 7:00 PM local time (centered on 6:12 PM to 6:18 PM).
IMPACTS
Minor flooding of very low-lying areas may be possible. Road closures or property impacts are not expected based on current data.
• Wind speeds around 10 mph from the south are moderate compared to winds observed in higher-category historical floods.
• Tidal height at or above 20 ft is a concern, but barometric pressure is significantly above the historical severe-flood threshold of ~992.8 hPa.
• No NOAA flood risk data are available for these dates, so the assessment is based solely on tide forecasts, observed pressures, and historical event comparisons.
• Similar or higher tides in the past with comparable pressures have been categorized as Category 3 events, indicating a cautious watch without anticipation of major flood damage.
CATEGORY 3
WHAT
Another high tide is expected around 20.2 ft with barometric pressure near 1004–1005 hPa (estimated). Conditions remain close to a flood event but are still not expected to cause notable property damage.
WHEN
Main high-tide window occurs late afternoon to early evening, centered around 6:54 PM.
IMPACTS
Low-lying areas may see brief standing water along beaches or very close to shore. Widespread flooding or significant property damage is unlikely.
• Wind speeds remain in the 8–10 mph range, lessening the chance of a more serious flood event.
• Even though tides surpass 20 ft, the pressure is well above the historically low levels that contributed to Category 4 or 5 floods.
• Historical events that reached Category 4 generally involved stronger winds or lower barometric pressures.
• No NOAA data suggests an active flood signal, supporting a milder risk classification.
CATEGORY 3
WHAT
High tide levels near 20.1 ft, with the lowest barometric pressure of the three days (about 1002.7 hPa). This slightly lower pressure is still well above critical flood thresholds, keeping conditions in a watch but not severe-damage scenario.
WHEN
Greatest concern late afternoon into evening, around 7:36 PM local time.
IMPACTS
Localized ponding in the most flood-prone spots along the immediate waterfront is possible. Substantial damage to exposed structures or wide-scale road closures are not anticipated.
• While the barometric pressure dips a bit more compared to Days 1 and 2, it remains higher than the ~992.8 hPa threshold linked with historical major flood events.
• Winds are not forecast to be high enough to amplify storm surge-driven coastal flooding.
• No NOAA flood likelihood data are available for this specific period, so this rating is based on tide, pressure, and historical comparisons alone.
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.
