Flood Watch

Redondo Beach, WA

Day 1: 2024-04-18

CATEGORY 3

WHAT Minor coastal flooding expected. Possible inundation of up to 1 foot above ground level near shorelines and low-lying areas.

WHEN From 2:00 AM to 3:00 AM PST and again from 1:00 PM to 2:00 PM PST.

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

ADDITIONAL DETAILS...

The barometric pressure during the high tides of 1013.77001953125 hPa and 1017.8699951171875 hPa, respectively, is significantly higher than the threshold associated with past flooding events. The tide heights are not reaching the critical levels observed in Category 4 or higher events. However, given the historical data, there is a potential for minor coastal flooding due to the tide levels being above 16 feet.

Day 2: 2024-04-19

CATEGORY 3

WHAT Elevated risk of coastal flooding. Inundation possible in very low-lying areas.

WHEN From around 2:30 AM to 3:30 AM PST and again from approximately 2:00 PM to 3:00 PM PST.

IMPACTS Potential for water encroachment into typically vulnerable areas. Some roads may be temporarily impassable.

ADDITIONAL DETAILS...

The barometric pressure readings of 1015.1400146484375 hPa and 1012.8599853515625 hPa during high tides are still above the critical threshold for severe flooding events. The tide heights are expected to be significant but not extreme enough to cause major property damage. The situation will be closely monitored due to the proximity of these values to historical Category 4 events.

Day 3: 2024-04-20

CATEGORY 4

WHAT Likely coastal flooding with potential for property damage in low-lying areas.

WHEN Highest risk near the high tide at approximately 3:00 AM PST.

IMPACTS Flooding of coastal properties and roads expected. Some damage to vulnerable structures possible.

ADDITIONAL DETAILS...

The barometric pressure is forecasted to drop to around 1008.6500244140625 hPa during the high tide, which is closer to the threshold observed in historical Category 4 events. Combined with a high tide level, this increases the risk of significant flooding impacts compared to the previous days.
