Redondo Beach, WA
CATEGORY 2
WHAT
No risk of flooding is expected on September 4. The highest projected tide (around 18.6 ft) will occur in the afternoon, but barometric pressure is moderately low at about 1006.96 hPa. NOAA’s outlook indicates a 0% flood likelihood for the day, suggesting no substantial threat of coastal flooding.
WHEN
Highest tide anticipated between approximately 3:00 PM and 4:00 PM local time.
IMPACTS
No coastal flooding is forecast. No significant impacts to property or travel are expected.
• The tide height, while above 16 ft, remains below the levels historically associated with moderate or severe events.
• The barometric pressure is not low enough (well above 992.8 hPa) to raise concern.
• NOAA’s Flood Likelihood for this date remains at 0.0%, consistent with minimal risk.
CATEGORY 3
WHAT
Close to a flood event and worth monitoring. A moderately high tide of about 18.9 ft coincides with a lower barometric pressure (near 1000.46 hPa), which could lead to minor coastal impacts. However, significant flood damage is unlikely.
WHEN
Highest tide is expected around 4:00 PM local time.
IMPACTS
Possible minor pooling of water in very low-lying areas. No major road closures or property damage are anticipated, but residents should remain alert.
• Though the barometric pressure is lower than Day 1, it remains noticeably higher than thresholds tied to past significant flooding (well below 992.8 hPa).
• The projected tide height is below Category 4 historical events, which typically involved tides of about 19.25 ft or higher combined with significantly lower pressure.
• NOAA’s Flood Likelihood for September 5 is still 0.0%, reinforcing that overall flooding risk remains low.
CATEGORY 3
WHAT
Conditions remain close to a flood event. The tide may reach around 19.1 ft, which is higher than the previous two days, and the barometric pressure (about 998.96 hPa) is the lowest in the three-day period. While worth monitoring, major flooding is not anticipated.
WHEN
Peak tide expected between approximately 4:00 PM and 5:00 PM local time.
IMPACTS
Minor flooding in the most flood-prone and low-lying areas is possible, but widespread or severe impacts are not likely.
• Although the barometric pressure is notably lower compared to Days 1 and 2, it is still higher than the historical thresholds often associated with more significant flooding events (near or below 992 hPa).
• NOAA’s statement of a 0.0% flood likelihood for this date further confirms low overall risk.
• Compared to past Category 4 and 5 events, this day’s tide level, while elevated, still falls short of the more extreme historical flood benchmarks.
