Flood Watch

Redondo Beach, WA

Day 1: 2025-04-16

CATEGORY 2

WHAT
No risk of coastal flooding is expected. Although the evening high tide may reach elevated levels (approximately 18.65 ft), the barometric pressure is not low enough to significantly increase flood risk, and NOAA’s flood likelihood remains at 0%.

WHEN
Primary high tide occurs around 8:00 PM local time.

IMPACTS
No flood impacts are anticipated for Day 1. Low-lying roads and shorelines should remain unaffected.

ADDITIONAL DETAILS...

• Compared to historical Category 3 events (e.g., 12/27/2023 with 17.46 ft tide but higher NOAA flood likelihood), this tide is slightly higher yet accompanied by a barometric pressure (~1004 hPa) above the severe threshold.
• NOAA’s current model indicates no flood risk (0% likelihood), reinforcing a lower category classification.
• Winds coming from the N/NNW are not expected to exacerbate tidal inundation.


Day 2: 2025-04-17

CATEGORY 2

WHAT
No risk of flooding is forecast. The maximal tide near 8:48 PM local time reaches around 18.53 ft, and barometric pressure is projected to stay around 1006.6 hPa, which is well above historically concerning low-pressure levels.

WHEN
Primary high tide occurs around 8:48 PM local time.

IMPACTS
No notable flooding impacts anticipated. Roads, beaches, and low-lying areas should remain clear of saltwater intrusion.

ADDITIONAL DETAILS...

• NOAA flood likelihood is 0%, indicating minimal concern for tidal flooding.
• Historical comparisons suggest higher tides generally require considerably lower barometric pressure or considerably stronger onshore winds to raise flood categories. Neither is present on Day 2.


Day 3: 2025-04-18

CATEGORY 2

WHAT
No risk of flooding is expected. The highest tide near 9:48-9:54 PM local time (around 18.34–18.35 ft) coincides with a barometric pressure of about 1004.7 hPa, still above thresholds historically associated with flooding events.

WHEN
Primary high tide occurs around 9:48–9:54 PM local time.

IMPACTS
No significant impacts to low-lying roads, beaches, or coastal infrastructure are anticipated.

ADDITIONAL DETAILS...

• While tides remain moderately high, the relatively stable barometric pressure and NOAA’s 0% flood likelihood rating indicate minimal cause for concern.
• Winds are not forecast to shift from the NNE/NNW to a more impactful onshore pattern.


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.
