Redondo Beach, WA
CATEGORY 3
WHAT
Close to a flood event but unlikely to cause notable property damage. Projected tides may reach around 19.6 ft during the early evening, with barometric pressure near 1001.45 hPa.
WHEN
Greatest risk window: approximately 6:00 PM to 8:00 PM local time.
IMPACTS
Minor flooding in very low-lying coastal areas is possible. Localized ponding of water on roads near the beach could occur. Most property damage is unlikely.
Based on historical comparisons, this scenario aligns with past Category 3 events. Although the tide approaches higher levels, the barometric pressure is not particularly low, suggesting a moderate but not severe threat.
CATEGORY 3
WHAT
Close to a flood event, similar to Day 1. Evening high tide of around 19.67 ft is forecast, with barometric pressure near 999.38 hPa—slightly lower than Day 1 but still above critical low-pressure thresholds.
WHEN
Greatest risk window: approximately 7:00 PM to 9:00 PM local time.
IMPACTS
Minor coastal flooding near the higher tides may lead to shallow standing water along shore roads and low-lying parking areas. Widespread property damage is not expected.
Although the barometric pressure is dropping slightly compared to Day 1, it remains above historically significant low-pressure values that have led to more substantial flooding. Resulting conditions appear consistent with other monitored Category 3 events.
CATEGORY 4
WHAT
Flooding is likely during the evening high tide. Though not expected to be catastrophic, moderate inundation could occur due to the combination of a tide near 19.72 ft and lower barometric pressure of about 994.9 hPa, which historically increases flood potential.
WHEN
Greatest risk window: approximately 7:00 PM to 9:00 PM local time.
IMPACTS
Water may encroach onto low-lying roads, walkways, and beachfront properties. Some road closures are possible in areas prone to coastal flooding. While extensive property damage is not anticipated, caution is advised.
Compared with historical records, this day’s lower barometric pressure in tandem with a fairly high tide height places the event in a Category 4 range. Although below the 21 ft tide levels seen in past severe floods, the magnitude of barometric pressure reduction heightens the likelihood of moderate flooding 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.
