Redondo Beach, WA
CATEGORY 3
WHAT
Tide levels near 20 feet are expected around the morning hours, accompanied by relatively higher pressure (above 1020 hPa). Overall flooding damage is unlikely, but water may crest close to typical flood thresholds in very low-lying coastal areas.
WHEN
The highest tides will occur from approximately 8:30 AM to 10:00 AM PST on December 26.
IMPACTS
Some very minor overflow along beaches or low-lying roads near the waterfront is possible. Impacts are expected to remain minimal, but it bears watching for any unusually low-pressure developments.
• Compared to past flood events, the barometric pressure remains fairly high, which counteracts the elevated tide height.
• NOAA forecasts a low flood likelihood (3.7%), further confirming that while water levels will be close to flood thresholds, major flooding is not anticipated.
• Historically, tides of about 20 ft accompanied by low pressure (<1002 hPa) have posed additional risk, but that scenario is not expected here.
CATEGORY 3
WHAT
Tide levels again approach 20 ft in the late morning. Barometric pressure is projected to dip into the 1015–1006 hPa range, still not near the more dangerous sub-1000 hPa conditions of past major events.
WHEN
Primary high tide risk occurs around 9:30 AM to 10:30 AM PST on December 27, with an additional weaker high tide in the late evening.
IMPACTS
Minimal coastal flooding remains possible in the most flood-prone spots. Peripheral roads, docks, and park areas along the immediate shore could see shallow water intrusion but are unlikely to experience significant property damage.
• NOAA reports a low (4.1%) daily flood likelihood, which supports only a brief, minor approach to flood thresholds.
• Although the late-evening barometric pressure is lower (near 1005.86 hPa), the corresponding tide height is much lower, reducing flooding concerns.
• These conditions are reminiscent of other Category 3 events on record where tide heights around 20 ft did not translate into damaging floods unless paired with much lower pressure or stronger onshore winds.
CATEGORY 3
WHAT
Morning high tide near 20 ft, with moderate barometric pressure around 1007 hPa. No dramatic wind shifts are forecasted.
WHEN
Highest water levels between about 9:30 AM and 10:45 AM PST on December 28.
IMPACTS
Limited impacts expected. Water levels could briefly reach some coastal edges but are unlikely to extend significantly into developed areas. Minor ponding along shorelines or walkway flooding is possible.
• Similar to Day 1 and Day 2, observed pressures are notably higher than in historical major flood events.
• The NOAA daily flood likelihood is at 2.8%, reinforcing that conditions approach but do not decisively surpass typical minor-flood thresholds.
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.
