Redondo Beach, WA
CATEGORY 3
WHAT
Tides near 20 ft and slightly lower-than-average barometric pressure around 997 hPa could bring water levels close to flood thresholds. NOAA indicates a low likelihood of actual flooding, but these conditions are worth monitoring.
WHEN
Highest concern around the high tide times of approximately 4:00 AM and 6:00 PM PDT on April 28.
IMPACTS
Minor inundation is possible right at the shoreline or very low-lying areas. Significant property damage is not expected.
• Barometric pressure is somewhat lower (997 hPa) but not near the 992.8 hPa threshold typically tied to higher flood risks.
• Historical Category 3 events had similar or lower tides (such as 17.46 ft with pressure 1006.1 hPa), so this is “close to a flood event” but unlikely to produce notable damage.
• NOAA Flood Likelihood for this date is effectively 0%, indicating minor-to-no chance of widespread flooding.
CATEGORY 3
WHAT
Early morning high tide near 19.7 ft coincides with barometric pressure around 993 hPa, closer to thresholds linked to past minor flood events. Winds remain moderate, reducing the risk of a more serious flood scenario.
WHEN
More attention around 4:30 AM PDT on April 29, where pressure dips to near 993 hPa, and again around 7:00 PM for another high tide, though pressure will rise slightly by then.
IMPACTS
Brief pockets of minor flooding could occur in low-lying coastal spots around these tide peaks. Damage to property is still unlikely.
• Although 993 hPa is relatively low, wind speeds will be much lower than in past Category 4 instances (winds ~20+ mph).
• NOAA’s forecast places the likelihood of flooding at just 0.1% for this date, reinforcing that significant inundation is not anticipated.
• Conditions resemble past Category 3 events where water levels were notable but typically did not cause major disruption.
CATEGORY 3
WHAT
High tides again approach 19.9 ft, combined with moderate pressure around 1001–1002 hPa. While not extremely low, it remains enough to merit close observation.
WHEN
Heightened watch around 5:00–6:00 AM and again at approximately 8:00 PM PDT on April 30 during peak tides.
IMPACTS
Minor over-topping of very low-lying areas is possible, but flood-related property damage is unlikely under the current forecast.
• NOAA flood probability remains near 0% for April 30.
• Similar tide heights have historically led to cautious monitoring but have not escalated to major flooding unless paired with extremely low barometric pressure or strong onshore winds.
• Winds are generally moderate and from a southerly direction, limiting additional storm surge potential.
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.
