Flood Watch

Redondo Beach, WA

Day 1: 2026-03-21

CATEGORY 2

WHAT
There is no significant flood threat based on the current data. Although the early morning high tide will be relatively elevated (around 19.8 ft), the barometric pressure is forecast near 1011 hPa—significantly higher than the low-pressure thresholds commonly associated with coastal flood events.

WHEN
Highest tide near 05:48 AM PST on 2026-03-21.

IMPACTS
Category 2 indicates no risk of flooding. Routine shoreline conditions are expected with no property damage or inundation anticipated.

ADDITIONAL DETAILS...

• NOAA’s Flood Likelihood stands at 0.1%, which is very low.
• The barometric pressure is substantially higher than levels historically linked with flooding (generally below ~992.8 hPa).
• Historical events with tides closer to or above 20 ft accompanied by much lower pressure (e.g., <1006 hPa) have been more prone to flooding, which does not match the current conditions.


Day 2: 2026-03-22

CATEGORY 2

WHAT
No substantial flood risk expected. Even though the morning high tide approaches 19.7 ft, barometric pressures near 1019–1024 hPa are higher than typical flood thresholds.

WHEN
Highest tides near 06:18 AM and 20:00 PM PST on 2026-03-22.

IMPACTS
Category 2 indicates no risk of flooding. No inundation issues are anticipated.

ADDITIONAL DETAILS...

• NOAA’s Flood Likelihood is 0.0%, implying very low chances of tidal flooding.
• Wind speeds are relatively light and not predicted from directions that historically exacerbate flooding (e.g., strong onshore winds).
• Compared to historical Category 3 or 4 events, both the expected tide height and the barometric pressure pattern do not align with flood-prone conditions.


Day 3: 2026-03-23

CATEGORY 2

WHAT
Continuing stable conditions with no notable indications of coastal flooding risk. The highest projected tide nears 19.3 ft, alongside barometric readings around 1016–1017 hPa, still well above the low-pressure benchmarks observed in past flooding episodes.

WHEN
Highest tides near 06:54 AM and 21:06 PM PST on 2026-03-23.

IMPACTS
Category 2 signals no risk of flooding. Normal high-tide behavior is expected, and no damage or inundation should occur.

ADDITIONAL DETAILS...

• NOAA’s Flood Likelihood is 0.0%.
• Compared with more significant historical floods—such as events exceeding 20 ft tides and pressures around or below 992.8 hPa—these conditions do not present a similar threat.
• Winds remain moderate and not from critical directions (e.g., strong W/NW) that have historically compounded flooding 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.
