Flood Watch

Redondo Beach, WA

Day 1: 2024-03-11

CATEGORY 3

WHAT Minor coastal flooding expected. Possible inundation of up to 0.5 feet above ground level near shorelines and low-lying areas.

*WHEN From 4:00 AM to 7:00 AM PST and from 4:00 PM to 7:00 PM PST.

IMPACTS Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible.

ADDITIONAL DETAILS...

The barometric pressure readings for the high tides on this day are significantly higher than the threshold that has historically indicated severe flooding events. The pressure readings of 1020.3 hPa and 1021.9 hPa during the high tides are indicative of more stable weather conditions, reducing the likelihood of a severe flood event. However, given the NOAA's low flood likelihood percentage and the distance to the flood threshold, there is still a minor risk for coastal flooding, especially during high tide times.

Day 2: 2024-03-12

CATEGORY 4

WHAT Coastal flooding likely with potential for property damage in vulnerable areas.

WHEN From 5:00 AM to 8:00 AM PST and from 5:30 PM to 8:30 PM PST.

IMPACTS Flooding of properties in low-lying areas, with possible damage to infrastructure. Road closures and disruptions to local communities are likely.

ADDITIONAL DETAILS...

The barometric pressure on this day is lower than on March 11th, with readings of 1013.4 hPa and 1016.3 hPa during high tides, which is closer to historical events that have resulted in flooding. Combined with NOAA's high flood likelihood percentage for this date, there is an increased risk of coastal flooding that may lead to property damage. The tide levels are not as high as the most severe historical events but are still significant enough to warrant concern.

Day 3: 2024-03-13

CATEGORY 2

WHAT Low risk of coastal flooding despite high tides.

WHEN From 5:30 AM to 8:30 AM PST and from 6:30 PM to 9:30 PM PST.

IMPACTS Minimal impacts expected with no significant flooding anticipated in coastal areas.

ADDITIONAL DETAILS...

On March 13th, the barometric pressure readings during both high tides are identical at 1014.0 hPa, which is higher than the threshold associated with major flooding events. The NOAA's low flood likelihood percentage further supports a reduced risk of flooding on this day. While the tide levels are elevated, they are not expected to reach a height that would cause significant flooding without the presence of other exacerbating weather conditions.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Residents 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. Consult local authorities or experts for final decision-making in flood-related situations and adhere to any evacuation orders or safety instructions provided by emergency services.
