Redondo Beach, WA
CATEGORY 3
WHAT A high tide reaching around 20.57 ft is expected early in the morning with relatively high barometric pressure (near 1018 hPa). NOAA’s projected flood likelihood is low (3.8%), suggesting conditions are close to a flood event but unlikely to cause damage.
WHEN Highest tide concerns extend from roughly 5:30 AM to 7:30 AM PST, then again late afternoon into early evening (around 4:30 PM to 6:30 PM PST).
IMPACTS Minor or negligible flooding in the most flood-prone low-lying coastal areas. No property damage is anticipated; however, residents in vulnerable spots should monitor conditions.
Compared to historic Category 4 events, the barometric pressure is substantially higher, and NOAA’s flood likelihood is notably lower. These factors reduce the likelihood of significant flooding. However, the tide height is still sufficient to warrant close observation, similarly to the 01/06/2025 Category 3 event.
CATEGORY 3
WHAT A morning high tide near 20.52 ft and barometric pressure around 1021 hPa. NOAA’s modeling states a 5% (“High”) flooding likelihood, but this percentage is still fairly modest compared to past flood-prone scenarios.
WHEN Main flood watch period from about 5:30 AM to 7:30 AM PST, with a lesser high tide in the early evening.
IMPACTS Close to a flood event; minor flooding of very low-lying shoreline areas is possible. Widespread or damaging flooding remains unlikely.
While NOAA flags a “High” flood likelihood for this day, it corresponds to a relatively low percentage chance. Historical Category 4 floods often featured significantly lower barometric pressures (around or below 1016 hPa) and notably higher NOAA flood likelihood scores (~10%). Consequently, Day 2 conditions align best with Category 3.
CATEGORY 2
WHAT An early morning high tide near 20.38 ft. However, the barometric pressure is forecast to be very high (around 1028 hPa), and NOAA’s flood likelihood is only 1.8% (“Low”).
WHEN Highest risk around 6:30 AM to 8:30 AM PST, with little concern later in the day.
IMPACTS No significant flooding risk is anticipated; this matches a Category 2 designation where the tide is elevated but prevailing weather conditions (high pressure and light winds) mitigate flooding.
Historical comparisons show similarly high tides but typically with far lower barometric pressures and higher NOAA flood likelihood when significant flooding has occurred. The combination of stronger high pressure and minimal wind drastically reduces any flood threat.
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.
