Flood Watch

Redondo Beach, WA


Day 1: 2025-03-24

CATEGORY 2

WHAT
No risk of flooding is expected. While tides will reach around 18 ft in the early morning, these levels remain well below the 21 ft threshold typically associated with flood events in Redondo Beach. Barometric pressure (around 1004–1005 hPa) is not sufficiently low to raise concern, and NOAA’s flood likelihood is 0%.

WHEN
Highest water levels around the early morning (approximately 02:00–03:00 AM PST) and again around midday, but neither are forecast to cause coastal inundation.

IMPACTS
No flood-related impacts anticipated. Normal tidal variations and minor ponding in very low-lying spots may occur, but no significant coastal flooding is expected.

ADDITIONAL DETAILS...

• Historical comparison: Past Category 3 events (e.g., 17.46 ft tide with some NOAA likelihood >0%) showed more concern. Today’s NOAA forecast and barometric pressure readings do not support a similar risk.
• Winds are light to moderate and do not align with conditions that have historically exacerbated flooding.


Day 2: 2025-03-25

CATEGORY 2

WHAT
Again, no flood risk is expected. Though the tide may briefly near 18.5+ ft (early morning), barometric pressure remains well above 992.8 hPa, and NOAA continues to indicate 0% flood likelihood.

WHEN
Highest tide anticipated overnight (around 02:30–03:00 AM PST) and midday (around 13:00 PM PST), but still below critical flood thresholds.

IMPACTS
No significant effects. Minor standing water in very low-lying areas could be observed, yet no notable flooding or property impacts are expected.

ADDITIONAL DETAILS...

• Barometric pressures remain in the 1003–1005 hPa range—higher than the levels typically seen with more severe coastal flooding.
• Wind direction and speeds are not converging with peak tides in a way that would normally cause flooding concerns.


Day 3: 2025-03-26

CATEGORY 2

WHAT
No risk of flooding is expected, even though the highest tide may approach 19 ft near 03:00 AM PST. Barometric pressure (~999–998 hPa) is somewhat lower but still not falling under the more critical 992.8 hPa benchmark. NOAA data indicates a 0% flood likelihood.

WHEN
Peak tide in the early morning hours (around 03:00 AM PST). A second afternoon high tide remains below typical flood thresholds.

IMPACTS
No coastal flooding impacts expected. Normal daily tide fluctuations may lead to minor water accumulation in extremely low-lying spots, but nothing indicative of flood damage.

ADDITIONAL DETAILS...

• While barometric pressure is lower than on Day 1 or Day 2, it is not low enough—and tide levels are not high enough—to trigger a flood threat.
• Historical Category 4+ events have involved tide heights above 19–20 ft coupled with much lower pressure (<992.8 hPa). Conditions for Day 3 do not match that profile.


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.
