Flood Watch

Redondo Beach, WA

Day 1: 2025-04-26

CATEGORY 3

WHAT
A moderately high tide of around 19.7 ft is expected in the early morning hours. Barometric pressure remains above the critical low threshold (around 1008 hPa), which suggests a reduced likelihood of significant flooding. Although conditions will be watched closely, flooding impacts are unlikely.

WHEN
Highest tidal levels around 02:54 AM to 03:30 AM local time.

IMPACTS
• Minor overflow in very low-lying coastal areas is possible, but not expected to cause damage.
• Roads close to shorelines could have brief water accumulations, but no closures are projected.

ADDITIONAL DETAILS...

• NOAA Flood Likelihood remains at 0%, indicating a low chance of significant inundation.
• Wind speeds are relatively low compared to past higher-category events.
• Historically, Category 3 events at Redondo Beach have sometimes involved tides around this height but with much lower barometric pressures or higher winds. Those factors are not present here.


Day 2: 2025-04-27

CATEGORY 3

WHAT
A tide reaching near 19.9 ft is forecast in the early morning through mid-morning hours. Barometric pressure will stay above 1008 hPa for the primary high tide periods, suggesting only marginal coastal flooding concern.

WHEN
Highest risk window from about 03:00 AM to 03:30 AM local time, with a secondary high tide later in the afternoon near 17:06 PM local time.

IMPACTS
• Some minor standing water in typically flood-prone areas directly adjacent to the shoreline.
• Little to no property damage is anticipated.

ADDITIONAL DETAILS...

• NOAA’s likelihood data continues to show 0% flood risk.
• Compared to past Category 4 events (with tides over 20 ft or barometric pressures near or below 992.8 hPa), the current conditions are not as severe.
• Winds remain relatively light and from the south, further reducing the chance of wind-driven flooding.


Day 3: 2025-04-28

CATEGORY 3

WHAT
High tides could exceed 19.7 ft early in the morning (around 04:00 AM) and again near 18:00 PM. Barometric pressure dips slightly toward 1005 hPa but remains well above the historical low-pressure benchmarks associated with more serious flood events.

WHEN
Primary tidal peak around 04:00 AM local time, with a secondary peak around 06:00 PM local time.

IMPACTS
• Coastal flooding close to the waterline is possible.
• No major flood damage is expected; slight ponding in low-lying spots near beaches may occur.

ADDITIONAL DETAILS...

• None of the forecast barometric pressures approach the 992.8 hPa range that has previously contributed to higher-category floods.
• NOAA indicates 0% flood likelihood.
• Wind speeds are modest and do not match the stronger onshore winds of past Category 4 or 5 events.


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.
