Flood Watch

Redondo Beach, WA

Day 1: 2025-04-19

CATEGORY 2

WHAT
Tides on April 19 are expected to reach around 18.2 ft by late evening, but the barometric pressure (~1008-1009 hPa) remains well above historically low thresholds associated with flooding. NOAA indicates a 0.0% flood likelihood. No coastal flooding is anticipated.

WHEN
Highest tide around 10:54 PM to 11:54 PM PST (22:54–23:54 local time).

IMPACTS
No flooding concerns expected for coastal roads or low-lying areas based on current data.

ADDITIONAL DETAILS...

Even though the high tide is relatively elevated, the pressure remains moderate and well above the ~992 hPa level commonly linked to flood risk. Historical events with similar or higher tides but low pressure have sometimes produced flooding, yet NOAA’s probability for this day is effectively zero, suggesting no threat of coastal inundation.


Day 2: 2025-04-20

CATEGORY 2

WHAT
Expected peak tides may again approach 18 ft in the late evening of April 20. Barometric pressure projections (1005–1008 hPa) are high enough to limit flood risk, and NOAA indicates a 0.0% flood likelihood.

WHEN
Primary high tide late evening (approximately 11:54 PM PST).

IMPACTS
No significant flooding is expected. Low-lying areas should remain unaffected.

ADDITIONAL DETAILS...

Although the tide height will be similar to Day 1, the pressure remains fairly stable and well above critical low thresholds. With NOAA’s continued clear forecast, conditions remain unfavorable for flooding.


Day 3: 2025-04-21

CATEGORY 2

WHAT
High tides on April 21 are expected to peak near or just above 18 ft around midnight and again lower (near 9–10 ft) in the afternoon. While the afternoon barometric pressure (~1002.75 hPa) is somewhat lower than previous days, it is still not near the historically low levels linked with significant flooding. NOAA reports a 0.0% flood likelihood.

WHEN
Highest water levels around midnight (12:00 AM PST), with another moderate tide in midafternoon (around 3:00 PM PST).

IMPACTS
No flooding concerns based on current data. Even the slightly lower barometric pressure in the afternoon remains above levels normally associated with notable flood events.

ADDITIONAL DETAILS...

Past moderate flood events required tidal heights nearer 20 ft and/or much lower barometric pressures (often below 1000 hPa). Comparatively, these three days show neither extreme tide nor sufficiently low pressure to raise concern, corroborated by NOAA’s minimal flood risk estimates.


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
