Redondo Beach, WA
CATEGORY 3
WHAT
Close to a flood event and worth monitoring, but unlikely to cause flood damage. Highest tide expected near 23:12 (approximately 19.4 ft) with moderately low barometric pressure around 999 hPa.
WHEN
Peak high tide near 23:00–23:59 PST.
IMPACTS
Potentially minor flooding of low-lying areas along the immediate coastline. Overall, no major property damage is expected, but it is prudent to stay alert if you live in or commute through areas that have experienced minor coastal flooding in the past.
Historical Category 3 events (such as 12/27/2023 with a 17.46 ft tide) had moderate barometric pressures and produced minor shoreline flooding. The tide here is slightly higher (near 19.4 ft), but the NOAA forecast indicates minimal flood likelihood. Winds are relatively calm compared to past Category 4 events. Therefore, this date is categorized as a 3: borderline conditions but unlikely to result in significant flood impacts.
CATEGORY 2
WHAT
No risk of flooding is expected. The notable high tide will be around 14:48 (about 17.7 ft) with barometric pressure around 1002 hPa, but NOAA’s forecast indicates a low likelihood of any coastal flooding.
WHEN
Peak high tide near 14:00–15:00 PST.
IMPACTS
No significant flooding impacts expected. Typical tidal fluctuations may produce minimal shoreline inundation in very low-lying spots, but nothing beyond normal conditions.
While the tide height is similar to some past events that reached Category 3 thresholds, the NOAA likelihood for flooding remains effectively 0%. Winds are light, and barometric pressure is higher than the more hazardous historical floods. Consequently, there is no substantial concern for coastal flooding on this day.
CATEGORY 3
WHAT
Close to a flood event and worth monitoring, but unlikely to cause flood damage. Another reasonably high tide of around 19.1 ft is expected, though barometric pressure is relatively stable near 1003 hPa.
WHEN
Peak high tide near midnight to early morning (around 00:00 PST) and again mid-afternoon.
IMPACTS
Minor flooding could affect very low-lying spots along the immediate shoreline. Widespread impacts to property or infrastructure are not anticipated, but local nuisance flooding is possible if wind waves coincide with peak tide levels.
Comparisons to historical Category 3 events show similar tide heights but with stable to higher barometric pressure, which moderates the risk. NOAA projections again indicate a low flood likelihood. Wind directions are not as strong or sustained as in previous Category 4 scenarios, limiting onshore water push.
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.
