Flood Watch

Redondo Beach, WA

Day 1: 2025-10-15

CATEGORY 2

WHAT
No coastal flooding is expected on this day. Tides will reach around 19 feet at their peak, which is below the thresholds observed in prior flood events. Barometric pressure is very high (above 1028 hPa), further reducing the likelihood of flooding.

WHEN
Peak high tide is expected around mid-afternoon (shortly after 1:00 PM local time), but no significant flooding impacts are anticipated.

IMPACTS
No flooding impacts expected. Normal coastal activity is anticipated with minimal disruption.

ADDITIONAL DETAILS...

• Barometric pressure remains well above historical low-pressure flood events (e.g., below ~992 hPa).
• NOAA Flood Likelihood is recorded at 0.0%, indicating no risk of tidal flooding.
• Wind speeds and directions are not expected to exacerbate water levels.
• Compared to historical Category 3+ events, current and forecast tide heights remain lower and the pressure is much higher.


Day 2: 2025-10-16

CATEGORY 2

WHAT
No coastal flooding is expected. While tide heights may approach 19 feet, barometric pressure is still quite high (above 1030 hPa), which significantly diminishes flood potential.

WHEN
Highest tides occur mid-afternoon, but they remain below the critical thresholds that have led to flooding in past events.

IMPACTS
No flooding impacts expected. Usual waterfront activities should remain unaffected.

ADDITIONAL DETAILS...

• The highest tides for this day are notably lower than the 20+ ft seen in Category 3 or higher events.
• NOAA continues to report a 0.0% flood likelihood for the region.
• Historically, low barometric pressure coupled with 21+ ft tides sets the stage for flooding, which is not currently the case.


Day 3: 2025-10-17

CATEGORY 2

WHAT
No coastal flooding is expected. Tides may again reach near 19 feet in the afternoon; however, very high barometric pressure (above 1027 hPa) indicates stable conditions.

WHEN
Highest tide is forecast early- to mid-afternoon (after 2:00 PM local time), with no significant flood triggers in place.

IMPACTS
No flooding impacts anticipated. All coastal activities can proceed normally.

ADDITIONAL DETAILS...

• Similar to Days 1 and 2, NOAA’s official flood likelihood remains at 0.0%.
• Wind direction and speed do not suggest any surge effect, particularly from W/NW.
• Historical data shows far lower pressure and significantly higher tide heights during flood events, neither of which applies here.


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.
