Flood Watch

Redondo Beach, WA

Day 1: 2025-01-18

CATEGORY 2

WHAT
No significant flooding concerns. Despite a relatively high morning tide (around 20 ft), barometric pressure remains above 992.8 hPa and NOAA’s forecasted flood likelihood is only 1.7%, indicating no substantial threat of flood damage.

WHEN
Highest tide near 08:12 AM PST.

IMPACTS
No notable coastal flood impacts expected. Low-lying areas should remain clear of inundation.

ADDITIONAL DETAILS...

• The barometric pressure for the high tide event is around 1011.78 hPa, which is not low compared to historical flood-causing events.
• Wind speeds are light, reducing onshore push.
• NOAA’s flood likelihood is minimal, indicating a low chance of coastal flooding.
• Historical Category 3 and 4 events typically involved higher tide heights (often >20 ft) coupled with much lower pressure or more significant wind speeds.


Day 2: 2025-01-19

CATEGORY 2

WHAT
Continued low flood risk. Morning and evening tides are moderately high but not expected to reach flood thresholds.

WHEN
Peak tidally influenced risk near 07:48–08:00 AM PST and again late evening around 20:42 PM PST.

IMPACTS
No flooding anticipated. Normal tidal fluctuations should not cause inundation in coastal or low-lying areas.

ADDITIONAL DETAILS...

• Barometric pressure near high tide is around 1019.58 hPa, well above historical flood-triggering lows.
• NOAA’s flood likelihood is 0.5%, reinforcing minimal flood chance.
• Light winds from the north/northeast do not favor additional water push onto shorelines.


Day 3: 2025-01-20

CATEGORY 2

WHAT
No risk of flooding. Although the morning tide nears 19–20 ft, prevailing conditions do not indicate any significant flood threat.

WHEN
High tides around 09:06 AM PST and 22:00 PM PST.

IMPACTS
No expected property damage or coastal inundation. Standard caution advised for routine high tide activity near harbors and beaches.

ADDITIONAL DETAILS...

• Barometric pressure for both high tides is around 1016.27 hPa.
• NOAA’s flood likelihood is only 0.1%, notably lower than even mild historic events.
• Comparisons with past Category 3–4 events show that wind speeds and/or pressures were substantially more conducive to flooding; neither factor here indicates heightened risk.


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.
