Flood Watch

Redondo Beach, WA

Day 1: 2024-04-04

CATEGORY 2

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

*WHEN From 01:00 AM to 03:00 AM PST and from 04:00 PM to 06:00 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 is significantly higher than the threshold that has historically led to severe flooding events. With pressures of 1019.47998046875 hPa in the morning and 1018.3599853515625 hPa in the evening, the risk of flooding is lower despite the high tide levels. The NOAA Flood Likelihood Analysis indicates a low likelihood of flooding for this day, with a flood threshold distance of -2.43m, which supports the forecast of a Category 2 event.

Day 2: 2024-04-05

CATEGORY 3

WHAT Elevated risk of coastal flooding. Potential for water levels to reach up to 1 foot above ground level in some areas.

WHEN From 01:00 AM to 04:00 AM PST and from 12:00 PM to 03:00 PM PST.

IMPACTS Moderate flooding of coastal areas, with some roads potentially becoming impassable. Property damage is unlikely but possible in very low-lying areas.

ADDITIONAL DETAILS...

On this day, the barometric pressure drops to around 1009.1500244140625 hPa during the morning high tide and further to 1005.1500244140625 hPa during the afternoon high tide, which is closer to historical events that have resulted in Category 3 flood events. The NOAA Flood Likelihood Analysis still indicates a low likelihood of flooding; however, the proximity to historical Category 3 conditions warrants a higher level of alertness.

Day 3: 2024-04-06

CATEGORY 2

WHAT Minor coastal flooding possible with water levels slightly above normal high tide marks.

WHEN From 02:00 AM to 04:00 AM PST and from 02:00 PM to 04:00 PM PST.

IMPACTS Low-lying areas and parks near shorelines may experience minor flooding. Disruption to outdoor activities in affected areas is possible.

ADDITIONAL DETAILS...

The barometric pressure on this day remains relatively stable at around 1010 hPa during both high tides, which does not indicate a significant risk of severe weather or flooding. The NOAA Flood Likelihood Analysis continues to show a low likelihood of flooding with a flood threshold distance of -1.69m, suggesting that any flooding would not be severe or widespread.

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.
