Redondo Beach, WA
CATEGORY 3
WHAT
Tides are forecast to reach around 19.7 ft (near midnight) with a barometric pressure of approximately 999.7 hPa, followed by an afternoon high tide near 18.2 ft under pressure of about 1001.3 hPa. These levels are close to earlier Category 3 events but should not cause significant or damaging flooding.
WHEN
Elevated tides are expected near 00:36 AM PDT and again around 03:36 PM PDT.
IMPACTS
• Minor tidal overflow may affect very low-lying and shoreline areas.
• Inconveniences such as ponding on coastal roads or parking lots could occur.
• Historical Category 3 events have shown tide heights ranging from about 17.5 ft to just over 20 ft, often with moderate barometric pressures.
• Winds are light, reducing the likelihood of severe wave action.
• Barometric pressures remain well above the critical ~992.8 hPa range for severe flooding risk.
CATEGORY 3
WHAT
Pre-dawn high tide (near 01:18 AM PDT) could reach approximately 19.6 ft at a barometric pressure of about 1000.2 hPa, followed by an afternoon high tide near 19.1 ft under a higher pressure of around 1005.0 hPa. Conditions remain similar to Day 1, with levels indicative of minor coastal flooding risk but not extensive damage.
WHEN
Higher tides are expected around 01:18 AM PDT and 04:36 PM PDT.
IMPACTS
• Minor flooding in low-lying and shoreline areas is possible.
• Brief impacts to beachfront walkways and minor overflow near boat docks.
• Tide heights are below the more serious 21+ ft levels historically tied to greater flood impacts.
• With barometric pressure remaining moderate, the weather does not align with higher-end historical flood scenarios.
• NOAA flood likelihood data was not available for these dates, limiting additional confirmation.
CATEGORY 3
WHAT
An early morning high tide near 02:06 AM PDT (around 19.5 ft) and a later peak near 17:30 PM PDT (around 19.8 ft) both occur under barometric pressures around 1005–1004 hPa. These conditions are close to prior Category 3 thresholds but do not match the tide/pressure extremes seen in more severe Category 4–5 events.
WHEN
Highest risk periods are near 02:06 AM PDT and 05:30 PM PDT.
IMPACTS
• Minor, localized flooding primarily around marinas, beach access points, and other very low-lying spots.
• Although peak tides approach 20 ft, the barometric pressure remains well above the low-pressure levels historically associated with more dangerous flooding.
• Expected wind speeds are light, mitigating additional wave-driven flooding.
• Historical comparisons suggest that these tides and pressures are unlikely to produce major or damaging coastal flooding.
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.
