Redondo Beach, WA
CATEGORY 2
WHAT
No risk of coastal flooding is expected. Tide levels will be elevated (peaking around midnight to early morning), but barometric pressure remains well above critical low-pressure thresholds, and NOAA’s flood likelihood analysis indicates a 0% chance of flooding.
WHEN
The highest tide is expected late on 2025-04-21 into the early hours of 2025-04-22 (around 00:54–02:00 local time). However, no flooding impacts are anticipated during this period.
IMPACTS
No flooding or property damage is expected. Normal tidal fluctuations should not affect roadways or low-lying coastal areas under current conditions.
• Barometric pressure near 1003 hPa around the highest tide, which is comfortably above historically severe low-pressure levels (e.g., below 992.8 hPa).
• NOAA’s Flood Likelihood for 2025-04-22 is 0.0%, with the tide well below the stated flooding threshold.
• Historically, events categorized at 3 or above combined significantly higher tide heights (over 20 ft) with much lower barometric pressures than currently observed.
CATEGORY 2
WHAT
No risk of flooding despite slightly lower barometric pressure compared to Day 1. Although tides will be high again, conditions remain insufficient for flooding.
WHEN
Key high tides occur around 01:30 and another near midday (12:48), but with mean surface pressures around 999–1001 hPa, still well above critical low-pressure flood indicators.
IMPACTS
No notable coastal flooding or property damage is expected. Shoreline areas and roads should remain unaffected.
• Tide heights near 19 ft are below the 20–21+ ft range typically associated with moderate to higher-category flood events in historical data.
• NOAA’s Flood Likelihood remains at 0.0% for 2025-04-23 with a comfortable margin below the flood threshold.
• Winds are forecast to be relatively light and from northerly directions, which have not historically contributed significantly to coastal flooding in this region.
CATEGORY 2
WHAT
Again, no risk of flooding is expected. Tides are projected to be fairly high, but barometric pressure is not low enough to raise concerns, and NOAA indicates no likelihood of flooding.
WHEN
Peaks near 02:00 and mid-afternoon (around 14:00), but neither tide nor pressure readings approach the historical benchmarks that have led to past flood events.
IMPACTS
No flooding or road closures anticipated. Conditions should remain stable along the shoreline with no threat to property.
• Although tide heights approach the upper teens (19+ ft), barometric pressure forecasts (999–1001 hPa) do not fall into the danger zone seen in severe historical events.
• NOAA data show 0.0% flood likelihood, and the remaining distance to threshold is considerable.
• Historical Category 3 or higher flood events featured both higher tides (often exceeding 20 ft) and substantially lower barometric pressures than what is forecast here.
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.
