Flood Watch

Redondo Beach, WA

Day 1: May 15, 2025

CATEGORY 3

WHAT
High tide near 19.2 ft is expected in the evening with barometric pressure around 1012 hPa. Conditions are close to a flood event and worth monitoring, but widespread or significant damage is not anticipated.

WHEN
Around 7:00 PM to 9:00 PM.

IMPACTS
Minor flooding in very low-lying areas is possible, but property damage is not likely.

ADDITIONAL DETAILS...

• Tides will rise to about 19.2 ft in the late evening, which is lower than typical Category 4 events in the historical record.
• Barometric pressure remains well above the critical 992.8 hPa threshold.
• Windspeeds are moderate and not expected to significantly worsen tidal impacts.
• No NOAA flood likelihood data is available for these dates.


Day 2: May 16, 2025

CATEGORY 3

WHAT
Evening high tide near 19.2 ft again with a barometric pressure around 1002 hPa, indicating close monitoring is prudent. Still, major flood damage is unlikely based on current data.

WHEN
Highest risk between 8:00 PM and 10:00 PM.

IMPACTS
Isolated minor flooding of low-lying coastal areas may occur. Little to no impact is anticipated on most properties.

ADDITIONAL DETAILS...

• Although pressure is somewhat lower than Day 1, it remains above the historically critical threshold of ~992.8 hPa.
• Projected tide heights are below the levels typically associated with Category 4 coastal flooding.
• No NOAA flood likelihood data is available for these dates.


Day 3: May 17, 2025

CATEGORY 3

WHAT
Evening high tide near 19.1 ft, with barometric pressure readings around 997 hPa in the morning. Despite the relatively lower pressure, the highest predicted tide is still below Category 4 criteria.

WHEN
Largest tide levels expected between 8:00 PM and 10:00 PM.

IMPACTS
Minor flooding in flood-prone parcels is possible, but severe or extensive property damage is not expected.

ADDITIONAL DETAILS...

• The morning high tides (around 16.9 ft) coincide with pressure near 997 hPa, but neither the tide height nor the pressure alone meets Category 4 conditions.
• Evening tides approach ~19.1 ft, similar to the prior two days, remaining below significant flood thresholds.
• No NOAA flood likelihood data is available for these dates.
