Flood Watch

Redondo Beach, WA


Day 1: 2025-08-16

CATEGORY 2

WHAT
No significant flood risk. While the evening tide will reach around 18.9 ft, barometric pressure is expected to remain relatively high (near 1016 hPa). NOAA’s flood likelihood forecast is at 0.0%, indicating minimal concern for tidal flooding.

WHEN
Peak tide near 9:42 PM to 10:00 PM local time.

IMPACTS
No anticipated flooding. Low-lying areas should remain clear, and property damage is not expected.

ADDITIONAL DETAILS...

• Tide levels, although higher than a typical day, are below the historical thresholds observed for more serious flood events.
• Winds are generally from the south/southwest and not strong enough to amplify surge conditions.
• Compared to past flood events categorized as Category 3 or higher, the pressure remains relatively high, and NOAA projects no flood likelihood.


Day 2: 2025-08-17

CATEGORY 2

WHAT
No significant flood risk; NOAA again forecasts a 0.0% flood likelihood. Maximum tide height near 18.4 ft is still below typical flood-trigger levels when paired with stable barometric pressure settings (about 1013–1015 hPa).

WHEN
Early afternoon and late evening high tides, peaking around 1:30 PM and 9:30–10:00 PM local time.

IMPACTS
No impacts to infrastructure or roadways are expected. Minor ponding near shoreline edges could occur but should remain well below concern levels.

ADDITIONAL DETAILS...

• Historical data shows more serious floods often align with tide heights exceeding 20 ft combined with notably lower pressure. Day 2 data do not approach those conditions.
• Winds remain fairly light and from directions less likely to cause wind-driven coastal water piling.


Day 3: 2025-08-18

CATEGORY 2

WHAT
Little to no flood risk. Tide levels will reach roughly 18.3 ft midday with slightly lower barometric pressure (~1005 hPa), but still far from the historically low pressure that contributed to damaging floods. NOAA rates flood likelihood at 0.0%.

WHEN
Highest tide around midafternoon (2:30–2:45 PM local time), with a secondary high tide shortly before midnight.

IMPACTS
No property damage or inundation expected. Coastal areas remain safe from any notable flooding.

ADDITIONAL DETAILS...

• Despite a lower pressure reading, it is still considerably higher than the critical 992.8 hPa threshold historically associated with more severe coastal flooding.
• Compared with past Category 3 or higher events, these tide heights (below 20 ft) and moderate pressure do not indicate concern.
• NOAA’s continued 0.0% likelihood reaffirms minimal flooding potential.


PRECAUTIONARY/PREPAREDNESS ACTIONS...

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.


CATEGORY KEY

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.
