Flood Watch

Redondo Beach, WA

Day 1: 2025-12-10

CATEGORY 3

WHAT
A relatively high tide of around 20.3 ft is expected mid-morning, paired with very high barometric pressure (above 1028 hPa). NOAA’s flood likelihood is listed as “High” at 5.3%, but this is still notably lower than past flood events. Overall, this suggests conditions are close to a flood event and worth monitoring, but widespread or significant flood damage is unlikely.

WHEN
Highest risk is near the midday high tide window, roughly from 9:00 AM PST to 11:00 AM PST on 12/10.

IMPACTS
• Minor tidal overflow in extremely low-lying coastal spots is possible.
• Streets or parking areas right at the water’s edge could see brief standing water.
• No major property damage is anticipated, though caution is advised for those in flood-prone areas.

ADDITIONAL DETAILS...

Historical comparisons such as the 01/06/2025 Category 3 event showed a similar tide height (around 20.68 ft) but lower barometric pressure (1020.47 hPa) and a higher NOAA flood likelihood score (11.3). Today’s higher pressure reading helps limit the severity. Although NOAA flags a possibility of minor flooding (5.3%), the current pressure suggests less intense conditions than many previous significant flood events.


Day 2: 2025-12-11

CATEGORY 2

WHAT
A tide near 20.1 ft is expected in late morning, but barometric pressure is extremely high (around 1032–1033 hPa), limiting any meaningful flood risk. NOAA’s likelihood of flooding is listed as “Low,” at 1.5%.

WHEN
Highest water levels occur around 10:30 AM PST on 12/11.

IMPACTS
• No risk of flooding is expected.
• Normal tidal action along the shoreline, with minimal concern for coastal roads or properties.

ADDITIONAL DETAILS...

Tide levels are comparable to the previous day, but with even higher atmospheric pressure and a lower NOAA flood probability. These factors align more closely with no-flood historical observations, supporting a Category 2 “No risk of flooding” forecast.


Day 3: 2025-12-12

CATEGORY 2

WHAT
Morning high tide near 19.8–19.9 ft, with a still high barometric pressure around 1029 hPa. NOAA’s flood likelihood remains “Low,” at approximately 0.6%.

WHEN
Peak tide occurs around 11:12 AM PST on 12/12.

IMPACTS
• No flood impacts are anticipated.
• Coastal areas remain unaffected aside from standard high-tide levels.

ADDITIONAL DETAILS...

Although tide heights approach 20 ft, barometric pressure is well above any historical flood-trigger threshold. NOAA data indicates very low flood potential. Comparisons to past events confirm that higher pressures and this moderate tide height pose little to no flood threat.


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.
