Flood Watch

Redondo Beach, WA


Day 1: 2025-12-29

CATEGORY 2

WHAT
No risk of flooding is expected. While the highest tide may approach 20.1 ft near midday (around 11:18 AM PST), the barometric pressure (approximately 1018 hPa) remains relatively high, and NOAA’s Flood Likelihood is only around 2%. These factors indicate minimal chance of inundation.

WHEN
From late morning to early afternoon (around 10:30 AM to 12:30 PM PST) when the tide height is at its peak.

IMPACTS
No significant flooding. At most, very minor ponding could occur in extremely low-lying areas, but conditions are not conducive to flood impacts or property damage.

ADDITIONAL DETAILS...

• Historically, flood events at or above Category 3 have had much lower barometric pressures or significantly higher NOAA flood likelihoods.
• Barometric pressure over 1000 hPa reduces flood potential, and the NOAA likelihood of 2% further confirms the low risk.
• Wind speeds are also expected to remain light, reducing the chance of coastal water intrusion.


Day 2: 2025-12-30

CATEGORY 2

WHAT
No risk of flooding is anticipated. Despite a tide again reaching around 20 ft near midday (about noon PST), the barometric pressure will be around 1032 hPa, which is quite high. NOAA projects a 1.8% flood likelihood.

WHEN
Late morning to early afternoon hours (approximately 11:00 AM to 1:00 PM PST) when the tide is at its highest.

IMPACTS
Minimal to no flooding expected. No road closures or significant inundation are anticipated given the stable, high-pressure system.

ADDITIONAL DETAILS...

• Comparison with past Category 3 or higher events shows those typically involve lower pressures or a higher NOAA flood likelihood.
• This day’s NOAA flood likelihood at 1.8%, combined with a high barometric pressure, suggests conditions will remain calm.


Day 3: 2025-12-31

CATEGORY 2

WHAT
Again, no risk of flooding is indicated. Peak tide near 19.98–20 ft around midday (about 12:48 PM PST) aligns with a barometric pressure reading near 1030 hPa and a very low (1.3%) NOAA flood likelihood.

WHEN
Midday period (roughly 11:30 AM to 1:30 PM PST) during the highest tide window.

IMPACTS
No anticipated flooding. Coastal areas should remain unaffected except for typical highest tide conditions along shorelines.

ADDITIONAL DETAILS...

• The continued presence of high-pressure patterns strongly suggests a stable situation with negligible flood risk.
• Winds are forecast to remain light, and NOAA’s flood likelihood is notably low.


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.
