Flood Watch

Redondo Beach, WA

Day 1: 2025-02-27

CATEGORY 2

WHAT
No flooding is expected. Tidal heights will approach but remain below critical levels, and barometric pressure is not sufficiently low to contribute to coastal flooding.

WHEN
Highest tide expected near 05:00 AM and again around mid-afternoon (around 03:54 PM).

IMPACTS
No apparent flooding impacts are anticipated at this time. Normal tidal fluctuations may cause slight ponding in the lowest-lying shoreline areas, but no significant property or infrastructure concerns are forecast.

ADDITIONAL DETAILS...

• The highest tide (~19.8 ft) remains under the 21 ft threshold that historically correlates strongly with flood events.
• Barometric pressure for the morning high tide is approximately 1000 hPa—above the critical 992.8 hPa threshold.
• NOAA’s Flood Likelihood for 02/27 is 0.0%, reinforcing a very low risk.
• Compared to the higher Category 5 event on 12/27/2022 (with tide ~22.3 ft and barometric pressure ~978.4 hPa), current conditions are significantly less severe.


Day 2: 2025-02-28

CATEGORY 2

WHAT
No flooding is expected. Tides will be moderately high but accompanied by relatively high barometric pressure.

WHEN
Peak tide is around 05:24 AM, with another higher tide in the late afternoon (approximately 04:48 PM).

IMPACTS
No major impacts are expected. Minor water accumulation along the immediate shoreline may occur during peak tide but should not lead to significant flooding issues.

ADDITIONAL DETAILS...

• Tide heights near 20.0 ft remain below flood-trigger levels, and the barometric pressure is forecast around 1016–1028 hPa, which is well above the historical low-pressure benchmarks.
• NOAA’s Flood Likelihood for 02/28 is only 0.2%, indicating a continued minimal risk from coastal flooding.
• Wind speeds from the forecasts remain generally light and not from a direction that has historically pushed water ashore in a threatening manner.


Day 3: 2025-03-01

CATEGORY 2

WHAT
No flooding is expected. While the tide height briefly approaches 20 ft, barometric pressure remains high, lessening the potential for flood conditions.

WHEN
Peak tide in the early morning (about 05:48 AM) and another peak in late afternoon (around 05:42 PM).

IMPACTS
Little to no impacts are anticipated. Typical high-water levels may be observed along beaches and low-lying coastal access points, but they are not expected to pose flooding threats to homes or roadways.

ADDITIONAL DETAILS...

• The morning and evening high tides both remain under 21 ft, and NOAA’s Flood Likelihood for 03/01 is 3.2%, still indicating minimal risk.
• Barometric pressure forecasts remain around 1025–1026 hPa, much higher than in historical flooding scenarios (e.g., ~992 hPa).
• Compared to Category 3 or above events—such as 01/06/2025 (20.68 ft tide, noticeably higher flood likelihood)—both the tidal height and flood likelihood here are lower.


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.
