Flood Watch

Redondo Beach, WA

Day 1: 2025-04-30

CATEGORY 2

WHAT
Tide levels are forecast to reach approximately 19.9 ft around 8:00 PM, which is relatively high; however, the barometric pressure remains well above 992.8 hPa, and NOAA forecasts a 0% flood likelihood. These conditions indicate no significant risk of coastal flooding.

WHEN
Highest tide occurs near 05:18 AM and again near 08:00 PM local time.

IMPACTS
No flooding is expected. Minor shoreline wave action could occur in very low-lying areas, but inundation or property impacts are not anticipated.

ADDITIONAL DETAILS...

• Barometric pressure readings are around 1003–1008 hPa, which is safely above the historical low-pressure thresholds often associated with coastal flooding in this area.
• Compared with past Category 3 or higher events, both tide height and NOAA flood likelihood data for this day are insufficient to suggest flooding.


Day 2: 2025-05-01

CATEGORY 2

WHAT
Despite tides nearing 19.7 ft in the evening, pressure remains above critical low levels, and NOAA continues to indicate a 0% flood likelihood. No notable wind influence from W/NW is apparent, further reducing any flood concerns.

WHEN
Peak tidal periods occur around 06:00 AM and near 09:00 PM local time.

IMPACTS
No flooding impacts are expected. Conditions will be monitored, but at present, inundation or damage is very unlikely.

ADDITIONAL DETAILS...

• Historically, higher flooding risks in Redondo Beach have involved lower barometric pressure combined with tides exceeding 20 ft. Both factors are below critical thresholds for Day 2.
• NOAA’s flood threshold analysis remains negative, indicating the water level is well below the risk elevation.


Day 3: 2025-05-02

CATEGORY 2

WHAT
Although the highest tide is projected to reach around 19.4 ft late in the evening, barometric pressure is still several millibars above historically noted flood-causing lows. NOAA data continues to show a 0% likelihood of flooding, suggesting stable conditions.

WHEN
Highest tide is expected near 06:54 AM and again close to 10:00 PM – 10:06 PM local time.

IMPACTS
No flooding risk. Shoreline areas and low-lying regions are unlikely to see any saltwater intrusion or need for flood precautions.

ADDITIONAL DETAILS...

• Day 3 compares similarly to recent moderate high-tide events but lacks the compounding low-pressure systems that led to past Category 3 and above scenarios.
• Wind directions are not positioned to push significant extra water onshore.


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.
