Redondo Beach, WA
CATEGORY 2
WHAT
No immediate risk of coastal flooding. Tide heights reach around 20.3 ft, but the barometric pressure remains quite high near 1028 hPa, reducing flood potential.
WHEN
Highest tide levels around early morning (near 07:00 AM PST) and again late afternoon (around 05:54 PM PST), though both occur under clear conditions and high pressure.
IMPACTS
No flooding expected. Normal tidal fluctuations with little to no impact on low-lying roads or properties.
This assessment results primarily from the unusually high barometric pressure (above 1028 hPa) offsetting the relatively elevated tide. NOAA’s low flood likelihood (4.0%) further supports minimal risk. Historical comparison shows that significantly lower barometric pressure (closer to or below 1000 hPa) and tides above 21 ft are typically needed to trigger higher flood categories.
CATEGORY 2
WHAT
Again, no significant risk of coastal flooding anticipated. The highest tide is near 20.4 ft, but barometric pressure remains above 1023 hPa, keeping overall flood potential low.
WHEN
Elevated tide around mid-morning (near 07:36 AM PST) and another peak late afternoon/evening (approximately 06:48 PM PST).
IMPACTS
No notable property or roadway flooding. Only the usual minor tidal effects along the shoreline in low-lying areas.
The NOAA forecast continues to show a low likelihood (4.9%) of flooding. While the tide is slightly higher compared to Day 1, it remains below the 21 ft benchmark, and the pressure is still far above the historical lows associated with flooding events.
CATEGORY 3
WHAT
Close to a flood event and worth monitoring, but unlikely to cause flood damage. Tide heights peak near 20.48 ft, coupled with moderately high barometric pressure around 1022-1023 hPa.
WHEN
Greatest tidal height around 08:00 AM PST and again in the early morning (around 02:30 AM PST), aligning with NOAA’s higher (7.9%) flood likelihood.
IMPACTS
Minor flooding in the most flood-prone, low-lying areas is possible. More pronounced splash-over or brief inundation along the immediate shoreline may occur, but damage to property or infrastructure is not expected based on current data.
Although pressure remains higher than in past severe events, the combination of peaked tide (around 20.5 ft) and NOAA’s increased “High” likelihood category (7.9%) nudges conditions toward Category 3. Historical Category 3 events often involved tides near or just above 20 ft and barometric pressures around or slightly above 1018–1020 hPa. Because our observed pressure is still well above historically significant flood thresholds, substantial impacts are not anticipated.
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.
