Redondo Beach, WA
CATEGORY 3
WHAT
Minor coastal flooding is possible during the morning high tide, though no significant damage is expected. The tide will peak around 20.28 ft with above-average barometric pressure levels.
WHEN
From approximately 7:30 AM to 8:30 AM PST on January 17, near the morning high tide.
IMPACTS
Minor flooding in low-lying areas and on shoreline roads is possible, but property damage is unlikely.
NOAA’s flood likelihood for January 17 is low (2.8%). Although the tide height exceeds 20 ft, the barometric pressure (around 1017–1018 hPa) is relatively high. Historically, Category 4 events combined tides above 20 ft with notably lower barometric pressures (around or below ~1002 hPa) and higher NOAA flood likelihoods (often above 8%). Therefore, while worth monitoring, the risk of damaging flooding remains low.
CATEGORY 3
WHAT
Another period of high tide near 20 ft may cause minor coastal flooding but is unlikely to result in significant harm or property damage.
WHEN
Morning high tide between around 7:30 AM and 8:30 AM PST on January 18.
IMPACTS
Low-lying coastal sections and roads may briefly experience minor inundation. Impacts are expected to remain limited, with no major closures anticipated.
The barometric pressure at high tide is projected near 1012–1018 hPa, higher than the thresholds typically associated with more serious flooding. NOAA forecasts a low flood probability (1.7%), further supporting a lesser risk. Winds are generally from the north or northeast rather than from the west, reducing onshore push and overall flood potential.
CATEGORY 2
WHAT
Little to no flooding is anticipated despite a moderately high tide just under 20 ft.
WHEN
Primarily around the early morning high tide hours on January 19, from about 7:30 AM to 8:30 AM PST.
IMPACTS
Minimal to no flooding is anticipated, and any impacts should be negligible.
NOAA indicates an even lower flood likelihood (0.5%). Barometric pressure is expected around 1020 hPa, which is sufficiently high to limit severe coastal flooding risk. Compared to historical Category 3 or higher events, the combination of higher pressure and lower flood-likelihood percentages suggests that any flood effects will be minimal.
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.
