Flood Watch

Redondo Beach, WA

Day 1: 2025-05-10

CATEGORY 2

WHAT
No coastal flooding is expected. Tides will reach approximately 18.3 ft, and while barometric pressure drops near 995.65 hPa around the afternoon high tide, NOAA’s forecast indicates a 0% flood likelihood for this date.

WHEN
Primary high tides occur near 02:48 AM and 04:48 PM PDT. Low overall flood risk persists throughout the day.

IMPACTS
No significant impacts anticipated. Normal activities along shorelines and low-lying areas are not expected to be disrupted.

ADDITIONAL DETAILS...

• Barometric pressures, though somewhat lower, remain above historically critical levels (near or below 992.8 hPa).
• Historical Category 3 or greater events typically featured higher tide heights (often above 20 ft) and/or significantly lower pressures.
• NOAA flood likelihood is 0%, reinforcing minimal flood concerns for Day 1.


Day 2: 2025-05-11

CATEGORY 2

WHAT
No flooding expected. Highest tides will again be under 19 ft, with barometric pressure around 994–995 hPa. NOAA flood likelihood remains at 0%.

WHEN
Peak high tides occur near 03:06 AM and 05:30 PM PDT. Conditions should stay stable throughout the day.

IMPACTS
No notable flooding impacts. Low-lying roads, beaches, and waterfronts should experience no flood-related closures or disruptions.

ADDITIONAL DETAILS...

• Although barometric pressure is lower than typical fair-weather readings, it is not sufficiently low to raise flooding concerns when paired with a tide below 20 ft.
• Compared to historical Category 3 or 4 flood events, the forecast tide levels and pressures remain less extreme.
• NOAA’s assessment of 0% flood likelihood aligns with no significant coastal flooding risk for Day 2.


Day 3: 2025-05-12

CATEGORY 2

WHAT
No flooding is anticipated. Tides may approach 18.8 ft around the evening with a barometric pressure near 993.97 hPa, which is slightly lower than on previous days but still above critical flood thresholds.

WHEN
Highest potential tidal peak is near 06:06 PM PDT; however, NOAA continues to project a 0% flood likelihood for this day.

IMPACTS
No disruptive impacts are expected. Shoreline areas should remain accessible, with minimal threat of tidal inundation or road closures.

ADDITIONAL DETAILS...

• Although the pressure is approaching the historically low range, it remains above the 992.8 hPa threshold typically linked with more serious flooding.
• Tidal heights are below the 20+ ft levels often seen in past Category 3 or higher flood events.
• NOAA’s forecast of 0% likelihood indicates very little risk for coastal flooding on Day 3.


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.
