Flood Watch

Redondo Beach, WA

Day 1: 2025-03-01

CATEGORY 2

WHAT
No risk of flooding is expected on March 1. Though tide heights approach 20 feet, barometric pressure remains very high (above 1026 hPa) which lessens the potential. NOAA data also indicates only a low probability (3.2%) of flooding.

WHEN
The highest tides occur around early morning (approximately 05:48 PST) and late afternoon (around 17:42 PST).

IMPACTS
No significant flooding is anticipated. Low-lying areas along the shoreline should remain unaffected under these conditions.

ADDITIONAL DETAILS...

• Historically, higher flood categories have correlated with noticeably lower pressure (< 1002 hPa) and tide levels above 21 ft. Current pressure values near or above 1026 hPa reduce the likelihood of flood events.
• Winds are generally light, and NOAA’s Flood Likelihood for March 1 (3.2%) aligns with minimal flood risk.


Day 2: 2025-03-02

CATEGORY 2

WHAT
No risk of flooding is expected on March 2. Despite a morning high tide around 20.4 ft, the barometric pressure remains unusually high (above 1031 hPa), which historically has been associated with minimal flood events.

WHEN
Highest tides occur around 06:18 PST and again near 18:42 PST.

IMPACTS
Areas that might normally see minor splash-over during lower pressure systems are unlikely to experience flooding given the elevated pressure and the low likelihood (4.7%) reported by NOAA.

ADDITIONAL DETAILS...

• Barometric pressure above 1030 hPa strongly suppresses the coastal flood risk compared to events with pressures near or below 1002 hPa.
• Wind conditions also appear light, further mitigating potential for water push or wave action that could otherwise exacerbate flooding.


Day 3: 2025-03-03

CATEGORY 2

WHAT
No risk of flooding anticipated on March 3. Morning and evening tides will approach 20 ft, but barometric pressure near or above 1031 hPa remains well above the historical flooding thresholds.

WHEN
Peak tides near 06:48 PST and again roughly at 19:48 PST.

IMPACTS
No notable coastal impacts. Typical shoreline activities should remain unaffected, and no additional precautions specific to flooding are indicated.

ADDITIONAL DETAILS...

• NOAA flood likelihood projections remain at 4.7% for March 3.
• By comparison, past Category 3 or higher events featured both higher tide levels (often exceeding 21 ft) and significantly lower pressure readings below approximately 1002 hPa.


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.
