Flood Watch

Redondo Beach, WA

Day 1: 2025-08-21

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.

ADDITIONAL DETAILS...

• 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.


Day 2: 2025-08-22

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.

ADDITIONAL DETAILS...

• 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.


Day 3: 2025-08-23

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).

ADDITIONAL DETAILS...

• 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%.


PRECAUTIONARY/PREPAREDNESS ACTIONS...
