Flood Watch

Redondo Beach, WA

Day 1: 2025-05-19

CATEGORY 2

WHAT
No risk of flooding is expected. The highest tide is anticipated near 19.1 ft around 23:00 PST, with barometric pressure of approximately 1002.4 hPa. NOAA’s forecast indicates a 0% flood likelihood for this date.

WHEN
Highest water levels around late evening (23:00 PST).

IMPACTS
No significant flooding impacts are anticipated. Minimal ponding of water in very low-lying spots along the shoreline may occur, but conditions do not suggest significant inundation.

ADDITIONAL DETAILS...
Though the barometric pressure is somewhat lower than average, today’s tide height does not exceed 20 ft. Historical comparisons show past moderate flood events (e.g., Category 3 or higher) generally coincide with tides above 20–21 ft and/or significantly lower pressure (below ~992–1000 hPa). Thus, based on current data and NOAA’s 0% flood likelihood, no disruption is expected.

Day 2: 2025-05-20

CATEGORY 2

WHAT
Again, no risk of flooding is expected. The highest tide is projected to approach about 19.2 ft late at night, but with a relatively higher air pressure of around 1014.1 hPa, NOAA indicates a 0% flood likelihood.

WHEN
Overnight hours (near 23:42 PST) will see the highest tide.

IMPACTS
No notable inundation or property impacts anticipated. Low-lying coastal areas should remain unaffected.

ADDITIONAL DETAILS...
Comparisons to historical Category 4–5 events, which involved tide heights over 20 ft and pressures below ~1002 hPa, indicate significantly lower danger here. Winds do not appear to be oriented from the W/NW in a way that would drive additional coastal surge.

Day 3: 2025-05-21

CATEGORY 2

WHAT
No risk of flooding is expected. Tides may hover around 19.3 ft in the late evening, with moderate pressure near 1011.7 hPa, and NOAA still projects a 0% flood likelihood.

WHEN
Late evening to nighttime (near or after 23:00 PST).

IMPACTS
No significant impacts forecast. Normal high-tide conditions are expected without flooding concerns.

ADDITIONAL DETAILS...
When compared to higher-category historical events, today’s tide levels remain below the 20–21 ft range more often associated with coastal flooding. The combination of steady pressure (above ~1011 hPa) and a favorable wind direction does not suggest conditions that would push water levels high enough to pose a flood threat.

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.
