Flood Watch

Redondo Beach, WA

Day 1: 2024-04-20

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 2:00 AM to 4:00 AM PST.

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

ADDITIONAL DETAILS...

The barometric pressure at the time of high tide is significantly higher than the threshold that has historically led to severe flooding events. However, the tide height is approaching levels that have previously resulted in minor coastal flooding. The wind direction from the west could contribute to water being pushed towards the coast, but the wind speed is not reported to be exceptionally high at this time. Comparing with historical data, particularly the event on 12/17/2022, the current conditions suggest a lower risk of severe flooding but warrant monitoring for minor impacts.

Day 2: 2024-04-21

CATEGORY 4

WHAT Coastal flooding likely, with potential for up to 1 foot of inundation above ground level in low-lying areas near shorelines.

WHEN From 2:30 AM to 4:30 AM PST and again from 3:00 PM to 5:00 PM PST.

IMPACTS Flooding of coastal areas, parks, and roads expected. Some road closures likely. Minor property damage possible in vulnerable locations.

ADDITIONAL DETAILS...

The barometric pressure is lower on this day, especially during the second high tide, nearing levels associated with more significant flooding events. The tide height is not reported but considering the pressure data and wind direction from the previous day, there is an increased risk of flooding. The NOAA flood likelihood remains low; however, given the proximity to historical Category 4 conditions, it is prudent to prepare for potential impacts.

Day 3: 2024-04-22

CATEGORY 3

WHAT Potential for minor coastal flooding with possible inundation near shorelines and low-lying areas.

WHEN From 3:00 AM to 5:00 AM PST and again from 4:00 PM to 6:00 PM PST.

IMPACTS Minor flooding of coastal areas, parks, and roads possible. Isolated road closures may occur.

ADDITIONAL DETAILS...

Barometric pressure remains relatively stable compared to Day 2 but still lower than Day 1. Without specific tide height data for this day, it is challenging to predict the exact impact; however, if we assume similar tide levels as previous days and consider the slightly higher barometric pressure than on Day 2, the risk appears to be similar to Day 1. Historical data suggests that these conditions are less likely to result in major flooding but should still be monitored closely.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Residents and visitors 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 advisories or evacuation orders that may be issued.
