Flood Watch

Redondo Beach, WA

Day 1: 2025-09-25

CATEGORY 2

WHAT
No risk of flooding is expected. Although tides are forecast to reach around 18.15 ft near 7:12 AM and 6:12 PM, the relatively high barometric pressure (ranging from approximately 1013 hPa to 1020 hPa) greatly reduces the potential for coastal flooding. NOAA’s official flood likelihood remains at 0.0%.

WHEN
Highest tides around 07:12 AM and 06:12 PM PDT on September 25.

IMPACTS
• No known flooding impacts.
• Normal coastal conditions are expected; low-lying areas should remain clear.

ADDITIONAL DETAILS...

Historical Category 3-4 events typically involved lower barometric pressure combined with higher tide peaks exceeding 19–20 ft. In contrast, these tides, while moderately high, are paired with stable and relatively high barometric pressure. NOAA data shows no significant flood risk, further indicating no coastal flooding threat.


Day 2: 2025-09-26

CATEGORY 2

WHAT
Again, no risk of flooding is anticipated as tides approach around 18.08 ft near 8:00 AM and 6:42 PM. Barometric pressure remains elevated (approximately 1018–1020 hPa), keeping conditions stable. NOAA rates flood likelihood at 0.0%.

WHEN
Highest tides around 08:00 AM and 06:42 PM PDT on September 26.

IMPACTS
• No anticipated effects on roadways or low-lying areas.
• Routine caution near shorelines is advised, but no flooding issues are expected.

ADDITIONAL DETAILS...

Comparisons with past flooding events show that more severe circumstances occur when barometric pressures drop near or below 992 hPa and tide heights exceed 20 ft. With this forecast, the higher barometric pressure and NOAA’s continued 0% flood likelihood confirm a minimal-risk outlook.


Day 3: 2025-09-27

CATEGORY 2

WHAT
No coastal flooding predicted. While tides may reach around 17.94 ft in the morning (about 08:54 AM) and 17.17 ft in the evening (about 07:12 PM), barometric pressure remains above 1013 hPa, and NOAA flood likelihood is 0.0%.

WHEN
Highest tides around 08:54 AM and 07:12 PM PDT on September 27.

IMPACTS
• No notable flood impacts expected.
• Normal tidal fluctuations with no hazard to local infrastructure.

ADDITIONAL DETAILS...

Historical reference points for flooding have included both higher tide levels (often 19–21+ ft) and notably lower barometric pressures (under ~1002 hPa). Because tides remain below major flood thresholds and surface pressures are relatively high, no flooding threat is indicated.


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.
