Redondo Beach, WA
CATEGORY 3
WHAT
Tides are forecast to peak near 19.8 ft late in the evening, accompanied by moderately low pressure (around 999.55 hPa). These conditions bring us close to a flood event, though significant flood damage is not expected.
WHEN
Highest risk near the late evening high tide around 23:54 PDT on June 20.
IMPACTS
Minor flooding of low-lying coastal areas is possible. No major property damage is anticipated. Monitor waterfront roads and walkways for temporary water accumulation.
Comparisons to historical Category 3 events (tide heights ranging from about 17 to 20 ft with pressures generally 1000 hPa or above) indicate similar conditions here. Although pressure is somewhat lower than typical high-pressure days, it is not near the critical lower threshold (~992.8 hPa). As such, a moderate but not severe water rise is likely along the shoreline.
CATEGORY 3
WHAT
Tides may approach 19.5 ft late in the evening, and barometric pressure readings in the upper 990s hPa are somewhat low but not critically so. This again places conditions close to a potential flood event without high likelihood of significant damage.
WHEN
Elevated tide conditions in the evening of June 21, peaking near or just before midnight.
IMPACTS
Minor flooding possible in the most vulnerable low-lying coastal areas. Significant or widespread property damage is unlikely. Beachfront roads should be monitored for shallow standing water.
A historical comparison with events featuring tides around 19–20 ft and moderately low pressure typically aligns with Category 3 conditions. While the barometric pressure briefly dips below 1000 hPa, it remains above the historically more critical threshold of ~992.8 hPa. No NOAA flood risk guidance is available for these dates to confirm a higher severity.
CATEGORY 3
WHAT
Forecasts show tides are again likely to peak near 19.7–19.8 ft. Barometric pressure is generally around 1000–1003 hPa, staying well above the very low range that has historically contributed to higher-category flood events.
WHEN
Expect the highest tidal levels during mid- to late-evening hours of June 22.
IMPACTS
Minor flooding is possible along the immediate shoreline and low-lying roads. Major property damage is not expected. A few locations prone to coastal flooding may see brief encroachment of water.
Although Day 3 remains similar to Days 1 and 2 in tide height, the relatively moderate barometric pressures—higher than typical severe-flood events—indicate only a close approach to flood thresholds. It does not match the low barometric pressures observed in Category 4 or 5 events on record.
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.
