Flood Watch

Redondo Beach, WA

Day 1: 2025-09-27

CATEGORY 2

WHAT
No risk of flooding is expected given the current forecasts. The highest observed tides reach around 17–18 ft, but barometric pressure remains near 1010 hPa, which is well above the low-pressure thresholds historically linked to flooding in this area. NOAA data indicate flood likelihood at 0.0%.

WHEN
Highest tides for Day 1 are around 08:54 AM and 07:12 PM local time.

IMPACTS
No significant flooding impacts are anticipated. Minor nuisance ponding right at the shoreline may be possible, but should not affect property or public safety.

ADDITIONAL DETAILS...

• Historical events with similarly elevated tides but low barometric pressure often recorded flood concerns; however, current moderate-to-high pressure readings remove that risk.
• NOAA’s analysis shows a distance to threshold of over 3 meters, reinforcing no flood risk.
• Winds are light and from the west/northwest, not strong enough to push additional water onshore.


Day 2: 2025-09-28

CATEGORY 2

WHAT
No risk of flooding is expected. High tides near 17–18 ft, but with barometric pressure around 1012–1014 hPa and NOAA’s 0.0% flood likelihood, conditions do not support coastal flooding.

WHEN
Highest tides for Day 2 are around 00:36 AM and 10:00 AM local time.

IMPACTS
No notable flooding impacts. Low-lying areas will remain unaffected, and there is no indication of any roadway or property inundation.

ADDITIONAL DETAILS...

• The barometric pressure is notably higher than in past moderate flood events.
• NOAA’s flood threshold distance for 09/28 remains at -3.38m.
• Light-to-moderate winds favor stable coastal water levels.


Day 3: 2025-09-29

CATEGORY 2

WHAT
No risk of flooding is expected. Although tides reach the mid-to-high 17 ft range, the barometric pressure near 1007–1011 hPa is not sufficiently low to raise flooding concerns. NOAA’s 0.0% flood likelihood confirms minimal risk.

WHEN
Highest tides for Day 3 are around 01:36 AM and 04:54 AM local time, with secondary peaks later in the morning.

IMPACTS
No flooding impacts are forecast. Normal shorelines, walkways, and roads are expected to remain dry.

ADDITIONAL DETAILS...

• Tide levels, though comparable to certain historical Category 3 tides, are not accompanied by low pressure or strong wind, mitigating any risk of coastal flooding.
• NOAA’s data still show a sizable gap from established flood thresholds (-3.46m).


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.
