Redondo Beach, WA
CATEGORY 3
WHAT
Tide forecasts indicate a high tide of approximately 20.2 ft in the evening, combined with moderately low barometric pressure near 1001–1004 hPa. This places conditions close to a flood event and worth monitoring, but unlikely to result in notable property damage.
WHEN
Key high tide of interest occurs between about 7:00 PM and 8:30 PM PST.
IMPACTS
Minor flooding in extremely low-lying areas cannot be entirely ruled out, but no major impacts to roads or property are expected at this time.
• NOAA’s official high tide flood likelihood is very low (0.1%), but the evening tide height is significant enough to warrant attention.
• Historic Category 3 events have had similar or slightly higher tide levels, although many also featured higher barometric pressures.
• Winds are generally light and mostly southerly, further reducing the likelihood of substantial coastal flooding.
CATEGORY 2
WHAT
Although the evening tide will again approach 20 ft, the barometric pressure for that period is higher (~1008 hPa), and NOAA’s flood likelihood remains effectively zero.
WHEN
Highest tide observed in the late evening, around 8:00–9:00 PM PST.
IMPACTS
No risk of flooding under these conditions. Wind speeds remain light, and tides—though relatively high—are not expected to produce inundation.
• Early morning low pressure (near 998 hPa) coincides with a much lower tide (~17–18 ft), further limiting the risk.
• Historical coastal flooding events in the Category 3–4 range typically had either much lower barometric pressures or higher tides (over 21 ft).
CATEGORY 2
WHAT
Tides remain elevated (around 19.8–20.0 ft) but are paired with relatively high barometric pressure (~1009 hPa) and negligible flood likelihood from NOAA (0.0%).
WHEN
Peak tide anticipated late evening, around 9:00 PM PST.
IMPACTS
No risk of flooding. Stable atmospheric conditions and low wind speeds lessen potential coastal impacts.
• Compared with historical moderate (Category 3 or 4) events, Day 3’s barometric pressure is significantly higher, reducing the threat of storm-induced flooding.
• NOAA’s forecast indicates no significant chances of coastal flooding.
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.
