Redondo Beach, WA
CATEGORY 2
WHAT
No coastal flooding is expected. Tides will reach around 18.6 ft at the morning high tide, but barometric pressure remains relatively high (around 1018 hPa), indicating no significant coastal flood risk.
WHEN
The highest tide occurs near 06:36 AM PST on March 18.
IMPACTS
No flooding impacts are anticipated. Normal marine conditions along shorelines and low-lying areas.
• Compared to historical Category 3 or higher events, both barometric pressure (over 1000 hPa) and observed tides are not sufficient to pose a flood threat.
• NOAA's Flood Likelihood for 2025-03-18 is listed as 0.0%, reinforcing that coastal flooding is unlikely.
• Winds remain modest and do not align with the stronger onshore flows seen in past moderate or severe flood events.
CATEGORY 2
WHAT
No flooding anticipated despite a fairly high tide (reaching around 18.2 ft). Barometric pressure near 1010 hPa remains well above thresholds known to contribute to coastal flooding around Redondo Beach.
WHEN
Peak tide occurs near 07:06 AM PST on March 19.
IMPACTS
No expected impacts to roads or property. Marine conditions are otherwise normal for this time of year.
• Although barometric pressure is lower than Day 1, it is still not in the historically significant range (<992 hPa) that has contributed to flood events.
• NOAA maintains a 0.0% daily flood likelihood for 2025-03-19.
• Past Category 3 and 4 floods showed both higher surge or tide levels and notably lower barometric pressure compared with current forecasts.
CATEGORY 2
WHAT
No coastal flooding is expected. Tides will be high (about 17.7+ ft), but barometric pressure is forecast around 1005 hPa, which is still significantly higher than thresholds typically associated with flooding events.
WHEN
Two high tides to note: near 07:30 AM PST and again around 10:12 PM PST on March 20.
IMPACTS
No notable impacts. Low-lying areas and shorelines will experience typical high-tide conditions, with no flooding projected.
• Even though the pressure is slightly lower on Day 3, it is not near historically low levels and NOAA reports a 0.0% likelihood of flooding.
• Historical Category 3 or higher events involved both stronger onshore winds and significantly lower barometric pressures below ~1002 hPa.
• Monitoring remains prudent, but forecast conditions do not meet or exceed known flood thresholds.
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.
