Flood Watch

Redondo Beach, WA


Day 1: 2025-08-18

CATEGORY 3

WHAT
Tides are projected to reach around 18.31 feet near mid-afternoon, with moderate barometric pressure (approximately 1003 hPa). NOAA’s outlook indicates a low flood likelihood (0%), but tide heights are still elevated enough to warrant attention.

WHEN
Highest tide near 14:42 PDT, with another high tide late in the evening around 23:48 PDT.

IMPACTS
While no significant damage is expected, there is potential for very minor water intrusion into exceptionally low-lying shore areas. Overall damage risk remains low, but conditions should be monitored in case of unexpected wind or weather changes.

ADDITIONAL DETAILS...

• Compared to historical events (e.g., 12/27/2023 Category 3 with a ~17.46 ft tide, 1006.1 hPa pressure), these tide and pressure levels are in a similar range, suggesting we are “close to a flood event” but still unlikely to see major impacts.
• NOAA’s Flood Likelihood for this date is 0.0%, strongly indicating minimal risk.


Day 2: 2025-08-19

CATEGORY 3

WHAT
Peak tide levels could approach 18.95 feet in the mid-afternoon, with slightly higher atmospheric pressure (~1007 hPa) than Day 1. NOAA continues to indicate a low flood likelihood of 0%.

WHEN
Highest tide on Day 2 is around 15:36 PDT.

IMPACTS
Similar to Day 1, only minor ponding or slight encroachment in the most vulnerable coastal spots is possible. Widespread flooding or property damage is unlikely.

ADDITIONAL DETAILS...

• Historically, tides near 19 feet with higher barometric pressures have not resulted in major flooding.
• NOAA’s data shows no significant risk this day, though it remains “close” enough to watch if weather patterns shift (especially wind direction/speed).


Day 3: 2025-08-20

CATEGORY 3

WHAT
Projected tide heights may reach about 19.31 feet in the late afternoon. Barometric pressure (~1006 hPa) remains relatively moderate. NOAA indicates a low likelihood, 0%, for flooding.

WHEN
Peak tide is expected around 16:24 PDT.

IMPACTS
Though tides are slightly higher than the prior two days, the still-moderate barometric pressure and 0% NOAA flood likelihood keep overall impacts minimal. Minor accumulation in the most susceptible areas only.

ADDITIONAL DETAILS...

• Even though the tide height is higher than the preceding days, the barometric pressure is not low enough to elevate this to a severe flooding risk.
• Comparisons to higher-category historical floods (often >20 ft tide or significantly lower pressure) confirm this remains unlikely to produce damage.


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.
