Flood Watch

Redondo Beach, WA

Day 1: 2025-05-30

CATEGORY 3

WHAT
A relatively high tide of around 20.0 ft is expected in the evening hours. Though NOAA’s official forecast indicates a low likelihood of flooding, the combination of a moderately low barometric pressure (~1006 hPa) and higher tide level puts conditions close to a minor flood threshold. Actual flood damage is unlikely based on both the historical tide-height comparisons and the official NOAA likelihood of 0%.

WHEN
Peak tide is anticipated from about 7:00 PM to 9:00 PM PST on May 30 (highest near 8:48 PM PST).

IMPACTS
• Minor roadway or parking lot ponding in very low-lying coastal spots is possible but not expected to cause damage.
• Little to no impact to property is expected.

ADDITIONAL DETAILS...

• Compared to past Category 3 events (e.g., January 6, 2025), today’s tide (about 20.0 ft) is somewhat similar, although NOAA’s flood likelihood remains at 0%.
• Barometric pressure is not extremely low (around 1006 hPa), but it is worth monitoring at the evening’s high tide.
• Winds are light from the NW and are not expected to exacerbate flood risk.


Day 2: 2025-05-31

CATEGORY 2

WHAT
Moderate high tides are forecast (about 19.8 ft at peak), with higher barometric pressure (~1015 hPa) than Day 1. NOAA estimates a 0% flood likelihood.

WHEN
Peak tide is anticipated late in the evening on May 31, around 9:30 PM – 10:30 PM PST.

IMPACTS
• No flooding is expected.
• Normal tidal fluctuations are anticipated; coastal areas should remain unaffected.

ADDITIONAL DETAILS...

• Historical comparisons show that tides near 19–20 ft typically do not produce flooding without significantly lower barometric pressure.
• Winds remain relatively calm, further reducing flood potential.


Day 3: 2025-06-01

CATEGORY 2

WHAT
High tide may reach about 19.6 ft in the late evening, with barometric pressure near 1008–1009 hPa, still higher than the critical low-pressure thresholds seen in severe historical events. NOAA forecasts a 0% flood likelihood.

WHEN
Peak water levels will occur roughly between 9:00 PM and 10:30 PM PST on June 1.

IMPACTS
• No flooding is expected.
• Routine tidal changes, with negligible impact on waterfront properties and infrastructure.

ADDITIONAL DETAILS...

• Though 19+ ft tides merit a watchful eye, the barometric pressure remains safely above historic low-pressure flood conditions (generally < 992 hPa).
• Calm westerly or northwesterly winds are not expected to push water inland significantly.


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.
