Flood Watch

Redondo Beach, WA


Day 1: 2025-11-19

CATEGORY 2

WHAT
Tide levels will reach around 19.05 ft in the early morning hours. Barometric pressure is near normal (approximately 1012.5 hPa), and winds remain light out of the SSE. NOAA’s Flood Likelihood is reported at 0%, indicating no substantial flood threat.

WHEN
Peak high tide around 05:24 PST.

IMPACTS
No flooding is anticipated. Low-lying areas along the immediate shoreline should remain unaffected based on current forecasts.

ADDITIONAL DETAILS...

• Tide height is notably elevated but below the 20+ ft levels typically seen in moderate flooding scenarios.
• Barometric pressure is not low enough to amplify tidal effects.
• Historical events with similar barometric pressure but higher tides have driven Category 3 or 4 conditions only when paired with lower pressure or stronger onshore winds.
• NOAA’s 0% flood likelihood further supports no significant risk of flooding.


Day 2: 2025-11-20

CATEGORY 2

WHAT
Peak tide expected to reach about 19.44 ft, with barometric pressure forecast around 1015.4 hPa, which is near or slightly above normal. Winds remain light, predominantly from the south. NOAA’s Flood Likelihood continues at 0%.

WHEN
Highest tide near 06:00 PST.

IMPACTS
No flooding is expected. Even in low-lying coastal spots, water levels should remain below any concerning thresholds.

ADDITIONAL DETAILS...

• Although the tide is relatively high, barometric pressure remains normal, limiting any surge potential.
• Winds are not forecast to come from a direction that would significantly push water onshore.
• Compared to historical moderate or major flooding events, both the tide height and the barometric pressure do not align with hazardous conditions.


Day 3: 2025-11-21

CATEGORY 2

WHAT
Morning high tide could reach around 19.66 ft, slightly higher than previous days. However, barometric pressure near 1014.78 hPa remains normal, and NOAA predicts a 0% flooding likelihood.

WHEN
Peak tide at about 06:36 PST.

IMPACTS
No flooding is anticipated. Low-lying areas are expected to stay clear of inundation concerns.

ADDITIONAL DETAILS...

• Historically, tides at or above 20 ft combined with much lower barometric pressure (under ~1000 hPa) have presented a greater flood risk.
• With normal pressure and benign wind patterns, the risk remains minimal.
• NOAA’s assessment confirms a low flood threat, consistent with on-site weather observations.


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

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.
