Flood Watch

Redondo Beach, WA

Day 1: 2024-12-13

CATEGORY 3

WHAT Minor coastal flooding possible. Tide levels are expected to reach up to 20.234 feet during high tide. No significant property damage is anticipated.

WHEN From 1:00 PM to 3:00 PM PST.

IMPACTS Minor flooding of low-lying areas, waterfront parks, and coastal paths. Isolated instances of water encroachment onto roads near the shoreline. No major disruptions expected.

ADDITIONAL DETAILS...

On December 13th, a high tide is forecasted at 2:00 PM with a peak of approximately 20.234 feet. The barometric pressure is around 1003 hPa, which is higher than during historical severe flood events. Wind speeds are low, averaging 2 mph from the west-northwest (297°). NOAA's Flood Likelihood is low at 2.6%, with water levels well below the flood threshold. Compared to the Category 3 event on December 27, 2023, which had lower tide heights and similar barometric pressure, the current conditions suggest a moderate risk that warrants monitoring but is unlikely to cause significant flooding.


Day 2: 2024-12-14

CATEGORY 3

WHAT Minor coastal flooding possible. High tides may reach up to 20.041 feet in the early morning hours. Conditions are similar to the previous day, with no major impacts expected.

WHEN From 4:00 AM to 6:00 AM PST.

IMPACTS Low-lying coastal areas may experience minor inundation. Waterfront parks and trails could have water encroachment. Daily activities are expected to proceed without significant interruption.

ADDITIONAL DETAILS...

On December 14th, the high tide at 5:00 AM is projected to peak at about 20.041 feet. The barometric pressure is slightly lower than Day 1, around 1000 hPa, but remains higher than levels associated with severe flooding events. Wind speeds are moderate, ranging from 8 to 14 mph, shifting from east-southeast (120°) to south-southwest (192°). NOAA's Flood Likelihood remains low at 1.4%, with a substantial margin below the flood threshold. While wind speeds are higher than on Day 1, they are not sufficient to elevate the flood risk beyond Category 3. Historical comparisons indicate that both tide heights and atmospheric conditions are within moderate levels of concern.


Day 3: 2024-12-15

CATEGORY 3

WHAT Minor coastal flooding possible due to higher than normal tides. Slightly elevated flood likelihood compared to previous days but still unlikely to cause major issues.

WHEN From 5:00 AM to 7:00 AM PST.

IMPACTS Minor flooding in low-lying coastal areas. Some waterfront access points may experience temporary water encroachment. Overall impact on the community is expected to be minimal.

ADDITIONAL DETAILS...

On December 15th, the high tide at 5:48 AM is expected to reach approximately 20.589 feet, slightly higher than the preceding days. Barometric pressure is high, averaging around 1023 hPa, indicating stable weather conditions not conducive to severe flooding. Wind speeds are decreasing throughout the day, starting at 11 mph from the south (189°) and dropping to around 4 mph by afternoon. NOAA's Flood Likelihood is higher at 9.5%, but this is primarily due to the higher tide levels rather than atmospheric conditions. The distance to the flood threshold remains significant at -0.59m. Compared to historical Category 4 and 5 events, the tide heights are lower, and the high barometric pressure further reduces flood risk. Therefore, the conditions align with a Category 3 event where flooding is close to occurring and worth monitoring but is unlikely to cause significant damage.

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.
