Redondo Beach, WA
CATEGORY 3
WHAT
Close to a flood event and worth monitoring. Minor, localized coastal flooding could occur around the time of the highest tide but is unlikely to cause substantial property damage.
WHEN
Highest risk near the high tide around 19:54 local time (tide ~19.24 ft).
IMPACTS
• Minor flooding of very low-lying coastal areas possible.
• Minimal or no property damage expected.
Analysis of historical data shows that tides around or above 19 ft can be significant, but the barometric pressure (around 1011 hPa) is not low enough to strongly increase flood risk. This places conditions closer to a Category 3 event rather than a more severe category.
CATEGORY 3
WHAT
Again close to a flood event and worth monitoring. Conditions remain similar to Day 1, with a slightly lower high tide (~19.19 ft), though barometric pressure (about 1004–1005 hPa) is somewhat lower.
WHEN
Highest risk near the high tide around 20:42 local time.
IMPACTS
• Potential for brief, minor water intrusion into low-lying locations.
• No major damages anticipated.
Although the barometric pressure is lower than Day 1, the tide is still below 20 ft. Historically, significantly lower pressures or higher tides (20 ft or more) correlate with more pronounced flooding. Thus, the situation remains a moderate concern.
CATEGORY 3
WHAT
Still near a flood event threshold. Two high tides of interest occur early in the day (~16.87 ft) with lower barometric pressure (~999.6 hPa) and later in the evening (~19.12 ft) likely with pressure near 1000–1001 hPa.
WHEN
• First notable high tide around 06:12 local time (16.87 ft)
• Second, higher tide near 21:24 local time (~19.12 ft)
IMPACTS
• Minor flooding of coastal walkways and isolated low-lying roads possible.
• Unlikely to cause significant damage to structures.
The slightly lower barometric pressure compared to previous days coincides with a tide near 19 ft, but still does not align with historically severe flood events (which generally exceed 20 ft or involve substantially lower pressures). As such, these conditions fit best within Category 3 criteria.
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.
