Flood Watch

Redondo Beach, WA

Day 1: 2024-03-28

CATEGORY 5

WHAT Major coastal flooding expected. Possible inundation of up to 18 feet above ground level near shorelines and low-lying areas.

*WHEN From 5:30 AM to 7:30 AM PST and again from 6:00 PM to 8:00 PM PST.

IMPACTS Significant flooding of low-lying areas, parks, and roads. Isolated road closures likely. Potential property damage due to high tide and low barometric pressure.

ADDITIONAL DETAILS...

The barometric pressure readings for the high tides on this day are significantly below the threshold of 992.8 hPa, which greatly increases the likelihood of flooding. The tide levels are also notably high, although not as extreme as the Category 5 event from 12/27/2022. However, given the lower barometric pressure, there is a substantial risk of flooding similar to a Category 5 event. The wind direction is not specified but should be monitored if it comes from the W/NW as it could push more seawater towards the coast.

Day 2: 2024-03-29

CATEGORY 3

WHAT Moderate coastal flooding possible. Potential for water levels to reach up to 17 feet above ground level in some areas.

WHEN From 5:45 AM to 7:45 AM PST and again from 7:00 PM to 9:00 PM PST.

IMPACTS Possible minor flooding of low-lying areas and parks. Roads near the shoreline may experience temporary closures or water accumulation.

ADDITIONAL DETAILS...

On this day, the barometric pressure increases significantly compared to Day 1, indicating less severe weather conditions and a reduced likelihood of extreme flooding. The tide levels are still relatively high but do not coincide with critically low barometric pressure, thus lowering the overall flood risk to a Category 3 event. The wind direction remains an important factor to consider for any changes in flood potential.

Day 3: 2024-03-30

CATEGORY 2

WHAT Low risk of coastal flooding. Tide levels are expected to be elevated but not at a height that poses significant flood risk.

WHEN Highest risk around high tide times, particularly from 6:00 AM to 8:00 AM PST and again from 8:00 PM to 10:00 PM PST.

IMPACTS Minimal impact expected with no significant flooding anticipated in coastal or low-lying areas.

ADDITIONAL DETAILS...

The barometric pressure on Day 3 is well above the threshold that typically indicates severe weather conditions that could lead to flooding. The tide levels are lower than on previous days, and without the combination of low pressure, the risk of flooding is minimal. This day's conditions do not closely resemble any historical events that resulted in significant flooding.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Residents and businesses near shorelines and low-lying areas should prepare for potential flooding on Day 1. Monitor forecasts closely and be alert for possible Flood Warnings. Consult local authorities for evacuation orders or safety instructions. For Days 2 and 3, stay informed about any changes in weather conditions or tide levels that could affect flood risks. Always err on the side of caution and have a plan in place for quick action if necessary.
