Redondo Beach, WA
CATEGORY 3
WHAT
A moderate evening high tide (peaking near 19.8 ft) combined with somewhat lower barometric pressure around 1001 hPa may bring water levels close to flooding thresholds. Minor coastal flooding in low-lying spots is possible but widespread flooding or significant property damage is not expected.
WHEN
From approximately 9:00 PM to midnight local time on June 17.
IMPACTS
Minor ponding of water along the immediate shoreline, low-lying roads, and nearby park areas. Inconveniences to beachgoers and those driving in areas near the waterfront are possible.
• Although the tide height is not as high as in historical Category 4 or 5 events, the barometric pressure is lower than normal, warranting close observation.
• Compared to past Category 3 events with similar or slightly higher tides but higher pressure, conditions remain in the moderate range.
• Winds are relatively light (around 4–6 mph), further limiting the risk of major flooding.
CATEGORY 3
WHAT
An evening high tide nearing 19.8 ft, with barometric pressure around 1003 hPa. Minor coastal flooding is possible, though significant flood damage is unlikely.
WHEN
From about 9:00 PM to midnight local time on June 18.
IMPACTS
Low-lying roads and beach areas may see brief periods of standing water, especially around peak tide. No major property damage is anticipated.
• Morning high tide on June 18 is lower (approximately 15.5 ft), with pressure around 997 hPa, which should not pose a flood risk.
• Wind remains moderate, below 10 mph, reducing the likelihood of wave-driven flooding.
• This category assessment aligns with historical Category 3 events where tides approached or exceeded 19 ft but fell short of the 20–21+ ft levels typical of higher categories.
CATEGORY 3
WHAT
Another high tide similar to the previous evenings (close to 19.8 ft), with barometric pressure near 1001–1002 hPa. Once again, this is near flood thresholds but not expected to cause major inundation or widespread damage.
WHEN
Late evening into midnight of June 19.
IMPACTS
Minor flooding may affect shoreside or low-lying roads, though no serious impacts are expected.
• Historical Category 4 and 5 floods tended to involve either significantly lower barometric pressure (well under 992 hPa), stronger onshore winds, or tide heights exceeding 20–21 ft. These factors are not present.
• Light winds (generally under 10 mph) will lessen storm surge risk.
• No NOAA flood risk data is available for these specific dates, so the analysis relies on tide, pressure, and wind comparisons with past events.
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.
