Flood Watch

Redondo Beach, WA

Day 1: 2025-05-28

CATEGORY 3

WHAT
A high tide near 20.28 ft is expected in the evening hours. Barometric pressure (approximately 1006.8 hPa) is not critically low, but it is lower than some previous days. This puts conditions near, yet still below, historically significant flood thresholds.

WHEN
Peak conditions around the evening high tide (roughly 7:00 PM – 8:00 PM PST).

IMPACTS
Minor nuisance flooding in very low-lying areas is not entirely out of the question, but no notable property damage is anticipated based on these tide and pressure levels.

ADDITIONAL DETAILS...

• Tide heights will be around 20 ft (below the 21 ft level often associated with actual flooding).
• NOAA Flood Likelihood is low (0.1%), well under thresholds linked to more dangerous flooding events.
• Winds appear moderate (generally SW at 10–16 mph), lessening the chance of water being pushed onshore.
• Compared to historic Category 4 events, barometric pressure is not low enough, and the tide is below 21 ft, indicating this will remain a watchful but less severe scenario.


Day 2: 2025-05-29

CATEGORY 3

WHAT
Another high tide near 20.24 ft is forecast for the evening. Barometric pressure (about 1004.1 hPa) remains moderately low but still above exceptionally critical levels, keeping the event in a watchful rather than severe range.

WHEN
Primary window to watch is the evening high tide (approximately 7:30 PM – 8:30 PM PST).

IMPACTS
Localized splash-over or very minor ponding is possible in the most vulnerable shoreline spots, but material flood damage is unlikely under current forecasts.

ADDITIONAL DETAILS...

• Tide remains below the 21 ft mark frequently associated with more impactful flooding.
• NOAA Flood Likelihood remains low (0.1%), supporting only minimal risk.
• Historical comparison to Category 4 events shows higher pressures and less wind than those more severe cases, suggesting limited concerns.


Day 3: 2025-05-30

CATEGORY 3

WHAT
High tide near 20.06 ft is forecast, coupled with a notable drop in barometric pressure (about 998.5 hPa). While this is lower than on Days 1 and 2, the tide remains under 21 ft. As a result, conditions approach but do not exceed typical flood-triggering levels.

WHEN
Highest concern during the evening high tide (roughly 7:30 PM – 8:30 PM PST).

IMPACTS
The lower barometric pressure could enhance water levels slightly, but with tide projections beneath 21 ft, significant coastal flooding or property damage is not expected.

ADDITIONAL DETAILS...

• Even though the pressure edges closer to historically low thresholds, the tide is still below levels that typically cause coastal inundations.
• NOAA’s Flood Likelihood remains negligible (0.0%), aligning with minimal flood potential.
• Less wind from the W/NW than in past Category 4 or 5 events, diminishing onshore water push.


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.
