Redondo Beach, WA
CATEGORY 2
WHAT
Tides will approach 20.1 ft in the late afternoon, but with relatively moderate barometric pressure (around 1011 hPa) and very low NOAA flood likelihood (0.0%), no flooding is expected.
WHEN
Highest tide expected near 18:00–19:00 PST.
IMPACTS
No inundation of roads or low-lying areas is anticipated. Impacts should remain minimal.
• Compared to historical Category 3 events, the NOAA flood likelihood of 0.0% strongly indicates minimal flood risk.
• Although the tide height is near 20 ft, the pressure is not significantly low (well above the ~992.8 hPa severe threshold) and wind speeds are not forecast to be high enough to raise concern.
• Overall, conditions align with a Category 2 rating, indicating no flooding expected.
CATEGORY 3
WHAT
Close to a flood event and worth monitoring, as the tide could exceed 20.2 ft around early evening while barometric pressure dips to about 1006 hPa. Actual flood damage is unlikely but the slightly lower pressure and higher tide warrant attention.
WHEN
Peak tide anticipated near 19:00–20:00 PST.
IMPACTS
Minor water encroachment along very low-lying shoreline areas is possible, but widespread flooding is not expected. Most impacts, if any, should remain limited to brief ponding near the waterfront.
• Historical Category 3 events have shown tide heights around or above 20 ft with moderate to high pressure. Here, the tide is near that threshold, and pressure is somewhat lower but still not near 992.8 hPa.
• NOAA’s official flood likelihood for this date is only 0.1%, reflecting a very low chance of actual flooding.
• On balance, conditions merit elevated awareness yet do not suggest significant or damaging flooding.
CATEGORY 3
WHAT
A combination of a high tide near 20.2 ft and the lowest barometric pressure of the three-day period (about 1000 hPa) makes this day worth close monitoring, though the NOAA flood likelihood remains at only 0.1%.
WHEN
Highest water levels expected near 19:30–20:30 PST.
IMPACTS
Minor inundation along the immediate shoreline could occur. Broad flood damage is unlikely, but mariners and residents in very low-lying areas should remain alert just in case localized impacts develop.
• While the tide height and lower pressure approach past Category 3 conditions, they are still well above the severe low-pressure threshold historically associated with higher categories.
• Wind speeds are not projected to be exceptionally high, limiting any additional storm surge effect.
• NOAA’s data aligns with only a 0.1% flood likelihood, suggesting that widespread flooding remains unlikely.
You should monitor later forecasts and be alert for possible Flood Warnings.
