Redondo Beach, WA
CATEGORY 3
WHAT
High tides peaking near 18.99 ft are anticipated in the late afternoon, with moderately low barometric pressure around 1011 hPa. Although NOAA floods likelihood is effectively 0.0%, the tide height is high enough to warrant monitoring, especially near shoreline areas.
WHEN
From mid to late afternoon (roughly 3:00 PM to 6:00 PM).
IMPACTS
Minor overflow into low-lying coastal areas is possible but widespread or damaging flooding is not expected.
Historical Category 3 events have featured tide levels in the 17–20 ft range with higher pressure—similar to this scenario. Given the moderate tides, relatively moderate wind speeds, and higher-than-critical barometric pressure, this setup suggests close-to-flood conditions without significant flood damage.
CATEGORY 3
WHAT
A slightly higher tide nearing 19.25 ft is forecast late afternoon to early evening. The barometric pressure (about 1008 hPa) remains above historically critical thresholds, and NOAA’s official flood likelihood remains at 0.0%.
WHEN
From approximately 4:00 PM to 7:00 PM.
IMPACTS
Minor tidal overflow is again possible along low-lying shoreline locations, but little or no significant property damage is anticipated.
Comparisons with previous moderate events (e.g., tides around 19 ft at barometric pressures above ~1005 hPa) have historically resulted in Category 3 conditions. With no strong onshore wind signal and a near-zero NOAA flood likelihood, watchfulness should continue, but major flooding is unlikely.
CATEGORY 3
WHAT
Tides could reach close to 19.4 ft, coinciding with a barometric pressure near 1004.5 hPa. Despite slightly lower pressure, NOAA’s flood outlook is still at 0.0%.
WHEN
Greatest tidal risk is mid to late evening (roughly 5:00 PM to 8:00 PM).
IMPACTS
Minor inundation may be observed in vulnerable shore areas. Significant property damage is improbable under these conditions, though caution is advised for beach-adjacent locations.
Historical Category 3 floods sometimes occur at or above 17–20 ft tides when barometric pressure is not extremely low. Even though Day 3’s tide is the highest of this three-day span, the pressure remains well above the 992.8 hPa threshold often seen in more severe events, keeping overall flood risk in the moderate monitoring range.
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; uncertain if major property damage will occur.
• Category 5: Likely to flood with property damage possible.
• Categories 6-7: Extremely high risk of flooding and significant property damage.
