Flood Watch

Redondo Beach, WA

Day 1: 2025-09-15

CATEGORY 2

WHAT
No risk of flooding is expected. Although the tide will reach around 18.3 feet in the early afternoon, barometric pressure remains above 1000 hPa, and NOAA flood likelihood for this date is reported at 0%. Under these conditions, historical comparisons indicate no significant threat of coastal flooding.

WHEN
The highest tide occurs late morning into early afternoon (peaking around mid-day), but no flooding impacts are anticipated during or after this period.

IMPACTS
• No inland flooding or property damage is expected.
• Beaches and immediate shoreline areas are not projected to experience flooding or overtopping.
• Normal marine activities may proceed without flood-related disruption.

ADDITIONAL DETAILS...

Comparing with historical Category 3 events, today’s tide levels are somewhat lower, barometric pressure is higher, and NOAA’s flood likelihood is minimal. Winds remain moderate from the north (generally under 15 mph). All indicators reflect no significant flood risk.


Day 2: 2025-09-16

CATEGORY 2

WHAT
Again, no flooding concerns are anticipated. Tides may approach the upper 18-foot range, but atmospheric pressure is still well above the critical low threshold, which greatly reduces flood potential. NOAA continues to forecast a 0% flood likelihood.

WHEN
Peak tides occur in the early morning and again near mid-day. No hazardous conditions are expected.

IMPACTS
• No observed or forecast inundation along shorelines.
• Roads and low-lying areas should remain unaffected.

ADDITIONAL DETAILS...

Historical events that reached Category 3 or higher involved either substantially higher tides (20+ feet) and/or much lower barometric pressures (around or below 992.8 hPa). Neither factor is present here. Wind speeds and directions remain benign for coastal flooding.


Day 3: 2025-09-17

CATEGORY 2

WHAT
No risk of coastal flooding. Although the high tide near mid-afternoon reaches around 19 feet, barometric pressure remains above 1013 hPa, and NOAA assigns a 0% flood likelihood.

WHEN
The primary high tide of interest occurs around 15:00 local time. No notable flooding impacts are expected.

IMPACTS
• No significant property damage or shoreline flooding.
• Coastal access points and roadways remain unaffected.

ADDITIONAL DETAILS...

Even though Day 3’s tide is higher than on Days 1 and 2, the pressure is still relatively high compared to past floods, and NOAA predictions remain low. This combination places the event below previously observed threshold levels for coastal flooding (e.g., Category 3–5 events historically required significantly lower pressure or tides exceeding ~20 feet).


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.
