Redondo Beach, WA
CATEGORY 2
WHAT
No flooding is expected along the shoreline on 2025-10-19. While afternoon high tide levels will reach near 19 ft, the barometric pressure is much higher than thresholds supportive of flooding (over 1033 hPa), and NOAA’s likelihood of coastal flooding is 0%.
WHEN
Highest tide around mid-afternoon (approximately 3:00 PM to 4:00 PM PST).
IMPACTS
No significant impacts are anticipated. Low-lying coastal roads and walkways should remain clear.
• Historical comparison: Past Category 3 or 4 events involved tides over 20 ft coupled with substantially lower barometric pressures (often near or below 1005 hPa). In contrast, this day’s pressure exceeds 1033 hPa, reducing risk.
• NOAA’s official Flood Likelihood for 10-19-2025 is 0.0%.
CATEGORY 2
WHAT
Again, no flooding is expected on 2025-10-20. Afternoon high tide will approach 19 ft but arrives under very high pressure conditions (above 1034 hPa), which keeps the flood potential negligible.
WHEN
Peak tide mid-afternoon (about 3:00 PM to 4:00 PM PST).
IMPACTS
Minor or no impacts to shoreline areas. Low probability of any roadway inundation or closures.
• Comparison with historical floods (Category 4 or higher) shows much lower pressures and/or greater tide heights. Here, pressure remains well above flood-risk thresholds.
• NOAA’s forecasted flood likelihood remains 0.0%.
CATEGORY 2
WHAT
No flooding expected on 2025-10-21. Although the tide reaches near 19 ft in the midafternoon, the barometric pressure remains around 1031–1032 hPa, significantly higher than the critical low-pressure benchmarks historically linked with coastal flooding.
WHEN
Peak tidal range near 4:00 PM PST.
IMPACTS
No coastal inundation or property impacts expected.
• All relevant indicators—high barometric pressure, moderate wind speeds, and 0% NOAA flood likelihood—suggest conditions remain safe.
• Even with higher tide levels, historically significant flood events required lower atmospheric pressure combined with tides over 20 ft.
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.
