Redondo Beach, WA
CATEGORY 2
WHAT
No significant flooding is expected. Although forecast high tides approach 20.3 ft early in the morning, barometric pressure remains high (around 1024–1026 hPa), and NOAA’s flood likelihood is rated low (3.8%).
WHEN
Highest tide near 05:06 AM PST.
IMPACTS
No notable coastal flooding impacts anticipated. Low-lying roads and shorelines should remain largely unaffected.
• Compared to past Category 3 events (e.g., 20.68 ft at 1020 hPa), today’s higher barometric pressure decreases the risk.
• NOAA data shows a 3.8% flood likelihood, supporting minimal flood concerns.
• Winds are light and generally from N/NE, further reducing any wind-driven tidal inundation potential.
CATEGORY 3
WHAT
Close-to-flood conditions are expected during the morning and afternoon high tides (roughly 20.7 ft). NOAA’s forecast indicates a higher flood likelihood (16.3%).
WHEN
• First peak: around 05:48 AM PST.
• Second peak: around 03:24 PM PST.
IMPACTS
Minor flooding of very low-lying areas may occur. Typically, impacts could include ponding on shore roads nearest to the water. Widespread property damage is not expected.
• Tide levels are similar to some past Category 3 events, but barometric pressure near or above 1024 hPa helps to limit severity.
• Winds remain relatively light and not strongly onshore.
• NOAA’s “High” daily flood likelihood suggests close monitoring even though pressure is high.
CATEGORY 3
WHAT
Another potential near-flood scenario. Tides could reach about 20.9 ft. Although barometric pressure is again high (around 1025 hPa), NOAA’s flood likelihood is 20.6%, which is notably elevated.
WHEN
• Early morning high tide near 06:30 AM PST.
• Late afternoon high tide near 04:24 PM PST.
IMPACTS
Minor coastal flooding in very low-lying areas is possible—particularly around marina entrances, seawalls, or vulnerable points along the shoreline. No major damage anticipated.
• This tide is slightly higher than Day 2, but also accompanied by high atmospheric pressure.
• No strong onshore wind (W/NW) is forecast, reducing additional surge risk.
• Historically, more severe flood events have involved lower barometric pressures below ~1016 hPa or strong winds.
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.
