Flood Watch

Redondo Beach, WA

Day 1: 2024-06-20

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 4:00 PM to 8:00 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 indicates severe weather conditions and potential flooding. With pressures of 1005.6 hPa and 1004.96 hPa during high tides, the likelihood of flooding is reduced compared to historical events that caused more severe flooding at lower pressures. The NOAA Flood Likelihood Analysis also indicates a low likelihood of flooding for this day, with a 0.0% chance and a distance to threshold of -2.12m, which supports the forecast of a Category 2 event.

Day 2: 2024-06-21

CATEGORY 3

WHAT Elevated risk of coastal flooding. Potential for up to 1 foot of inundation above ground level in vulnerable areas.

WHEN From 5:00 PM to 9:00 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 during high tides is lower than on Day 1, with readings of 1000.77 hPa and 1001.71 hPa, which brings us closer to conditions that could support a flood event. However, these values are still above the critical threshold observed in past significant flood events. The NOAA Flood Likelihood Analysis maintains a low likelihood rating for this day as well, which suggests that while there is an elevated risk compared to Day 1, it is not expected to reach the severity of historical Category 4 or higher events.

Day 3: 2024-06-22

CATEGORY 3

WHAT Continued elevated risk of coastal flooding with potential for up to 1 foot of inundation above ground level in vulnerable areas.

WHEN From 5:30 PM to 9:30 PM PST.

IMPACTS Similar to Day 2, moderate flooding in coastal zones may occur, with some roads at risk of closure due to water levels. Low-lying properties should be vigilant.

ADDITIONAL DETAILS...

The barometric pressure on Day 3 shows a slight increase compared to Day 2 during high tides, with readings of 1001.95 hPa and 1002.48 hPa. These values are still not indicative of severe weather conditions that would lead to major flooding events based on historical data comparisons. The NOAA Flood Likelihood Analysis continues to indicate a low likelihood of flooding for this day as well, supporting the Category 3 forecast.

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 the most current information and adhere to any advisories or evacuation orders that may be issued.
