Flood Watch

Redondo Beach, WA

Day 1: July 27, 2025

CATEGORY 2

WHAT
Tides will reach approximately 19.7 ft in the evening hours (around 7:24 PM local time), with a moderate barometric pressure near 1005 hPa. NOAA’s flooding likelihood remains at 0%, indicating no risk of coastal flooding.

WHEN
Peak tide is expected around 7:24 PM local time on July 27.

IMPACTS
No shoreline flooding impacts are anticipated in low-lying areas. Roads and parks along the immediate waterfront should not experience inundation under these conditions.

ADDITIONAL DETAILS...

• The highest tide for Day 1 (approx. 19.7 ft) is below the 21 ft level historically associated with more significant flooding.
• Barometric pressure (near 1005 hPa) is not especially low and does not closely match past flood events of higher categories.
• NOAA’s Flood Likelihood Analysis for July 27 remains at 0%, further supporting Category 2 (no flood risk).


Day 2: July 28, 2025

CATEGORY 3

WHAT
An evening high tide near 19.6 ft combined with a lower barometric pressure (approximately 995 hPa) brings conditions close to a minor flood event. However, flooding would be unlikely to cause damage given the current forecast.

WHEN
Peak tide is expected around 7:54 PM local time on July 28.

IMPACTS
Little to no property damage is expected. Low-lying areas may experience occasional water pooling, but impacts appear minimal at this time.

ADDITIONAL DETAILS...

• While the barometric pressure is lower than Day 1, the tide height remains under 20 ft.
• Historically, tides below 21 ft and pressures above ~992 hPa have tended to produce only minor or no flooding if wind conditions are not extreme.
• NOAA’s Flood Likelihood Analysis for July 28 is also at 0%, aligning with a lower chance of coastal flooding.
• Winds are forecast out of the north or northwest at modest speeds, not strongly favoring onshore water buildup.


Day 3: July 29, 2025

CATEGORY 4

WHAT
A high tide near 19.3 ft will coincide with a notably low barometric pressure (about 992.25 hPa). This combination increases the potential for coastal flooding, although major property damage is not anticipated.

WHEN
Peak tide occurs around 8:18 PM local time on July 29, with the lowest barometric pressure forecast around the same period.

IMPACTS
Coastal roads, parking lots, and low-lying shoreline properties could see moderate flooding. Some areas may need minor protective measures (e.g., sandbags in immediate waterfront zones).

ADDITIONAL DETAILS...

• Historical reference (e.g., January 7, 2022) shows that similar tide heights paired with barometric pressure in the 992–993 hPa range correlated with moderate flood events.
• Despite NOAA’s reported 0% likelihood, the notably low pressure at a relatively high tide height suggests close monitoring.
• Winds are forecast primarily out of the N/NNW. Even though this may reduce onshore push compared to southerly winds, the very low pressure remains a factor.


PRECAUTIONARY/PREPAREDNESS ACTIONS...

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 KEY

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.
