Redondo Beach, WA
CATEGORY 2
WHAT
No risk of flooding is expected. Tides are forecast to peak near 19.76 ft, remaining below the 21 ft threshold typically required to elevate the flood risk in this region. Barometric pressure is around 1010 hPa, which is well above critical low-pressure levels historically associated with higher flood potential. NOAA estimates the flood likelihood at only 0.1%.
WHEN
No significant flooding concerns are anticipated throughout the day.
IMPACTS
• No flooding impacts are expected in low-lying or normally flood-prone areas.
• Typical shoreline activities should be unaffected.
Historical Category 3 or higher flood events in this area usually involved tides above 20 ft combined with much lower barometric pressure and higher wind speeds. Despite a moderately high tide, today’s relatively higher pressure and light winds keep the flooding risk minimal.
CATEGORY 2
WHAT
No risk of flooding is expected. The highest tide will be just under 20 ft (about 19.90 ft), with barometric pressure around 1021 hPa. NOAA flood likelihood remains very low at 0.2%.
WHEN
No significant flooding concerns are anticipated throughout November 30.
IMPACTS
• No flooding impacts expected.
• Normal activities along the shoreline should be unhindered.
Although the tide height is relatively high, the barometric pressure is solidly above the low-pressure thresholds that historically correlate with flood events in Redondo Beach. Additionally, the wind speeds forecast are light, which reduces the chance of water piling up along the coast.
CATEGORY 2
WHAT
No risk of flooding is expected. Tide levels may briefly exceed 20 ft (approximately 20.05 ft) but remain below the critical 21 ft threshold necessary to heighten flood risks. Barometric pressure is forecast near 1023 hPa, well above the historical low values typically linked to flood events. NOAA indicates a 1.8% flood likelihood, still classified as “Low.”
WHEN
No significant flooding concerns are anticipated on December 1.
IMPACTS
• No predicted flooding in coastal or low-lying roadways.
• Expect normal beach conditions without significant inundation.
Comparisons with past Category 3 or higher incidents show that bigger floods generally develop when tides exceed 21 ft in conjunction with notably low air pressure (around or below 992.8 hPa), or when strong onshore winds coincide with high tides. Neither factor appears present for December 1.
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.
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.
