Redondo Beach, WA
CATEGORY 3
WHAT
Coastal water levels will be relatively high in the afternoon, coming close to—though likely not exceeding—flood thresholds. Minor inundation could occur near shorelines and low-lying spots, but material damage is not expected.
WHEN
Peak concern around high tide (approximately 4:30 PM to 5:30 PM local time).
IMPACTS
• Possible minor overflow onto beach access points, parking areas, and low coastal roads.
• Overall flood damage is unlikely given current barometric pressure and NOAA’s low flood likelihood forecast.
• The highest tide on 2025-08-21 is forecast to reach about 19.46 ft with a barometric pressure near 1003 hPa, which is not exceptionally low.
• By comparison, Category 4-type historical events typically had tides in the 20 ft+ range paired with lower barometric pressures.
• NOAA has indicated a 0.0% daily flood likelihood for this date, further suggesting only minor impacts if any.
CATEGORY 3
WHAT
Afternoon tide levels will again be elevated, approaching, but likely not crossing, flood thresholds. Minor effects could be felt in low-lying coastal areas.
WHEN
Peak concern near high tide (approximately 4:30 PM to 5:30 PM local time).
IMPACTS
• Some shallow inundation in coastal recreation areas and shoreline access points is possible.
• No significant property damage is expected, as barometric pressure remains above notably low thresholds.
• Maximum tide around 19.48 ft with pressure near 1003 hPa—a similar pattern to Day 1.
• Historically, even slightly lower pressure (below ~992 hPa) or tides exceeding 20 ft have driven more serious flooding.
• NOAA’s flood likelihood for 2025-08-22 is 0.0%, suggesting little to no broader flooding concerns.
CATEGORY 3
WHAT
Water levels will remain high during the afternoon high tide, presenting a near-flood scenario, though damaging inundation is not anticipated.
WHEN
Heightened risk timeframe typically from about 4:30 PM to 5:30 PM local time.
IMPACTS
• Minor ponding or overwash in usual trouble spots along the immediate shoreline.
• Property damage is not expected due to moderately low tides (below 20 ft) and a higher barometric pressure (about 1004 hPa).
• The highest forecast tide on 2025-08-23 is roughly 19.42–19.43 ft.
• Barometric pressure around 1003–1004 hPa is not in the low range known to heighten flood severity substantially.
• NOAA categorizes the day’s flood likelihood as 0.0%.
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.

Category 5: Likely to flood and cause property damage.
Categories 6-7: Extremely high risk of flooding and property damage.
