Flood Watch

Redondo Beach, WA

Day 1: 2024-07-28

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 high tide times around 11:12 AM and 10:18 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 has historically indicated severe flooding (1001.69 hPa and 1003.38 hPa vs. the critical threshold of 992.8 hPa). The tide heights are not reaching the levels seen in Category 4 or 5 events from historical data, suggesting a lower risk of severe flooding. However, the tide height is still substantial, and with the NOAA's Flood Likelihood Analysis indicating a low likelihood, there is a potential for minor coastal flooding, especially during high tide times.

Day 2: 2024-07-29

CATEGORY 2

WHAT Coastal conditions are expected to be relatively stable with a very low risk of flooding.

WHEN Throughout the day, with attention to high tide times around 3:36 AM and 1:12 PM PST.

IMPACTS No significant impacts expected. Normal tidal conditions with no anticipated disruption.

ADDITIONAL DETAILS...

The barometric pressure remains stable and relatively high (1001.26 hPa and 1001.89 hPa), indicating no significant weather disturbances that could lead to flooding. The tide heights are lower than those observed on Day 1, further reducing the risk. NOAA's Flood Likelihood Analysis continues to show a low likelihood of flooding for this day.

Day 3: 2024-07-30

CATEGORY 4

WHAT Elevated risk of coastal flooding due to higher tides and lower barometric pressure.

WHEN High tide times around 4:18 AM and 9:00 AM PST are of particular concern.

IMPACTS Potential for moderate flooding of coastal areas, roads, and properties close to the shoreline. Precautionary measures recommended for vulnerable structures.

ADDITIONAL DETAILS...

On this day, the barometric pressure drops closer to the threshold that increases flood risk (999.29 hPa and 1000.42 hPa), especially when paired with high tides over 16 feet. The wind direction is not provided but considering the lower pressure and higher tides, there is an elevated risk compared to the previous days. This forecast aligns more closely with historical Category 4 events, although still not reaching the most severe historical thresholds.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Residents 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.
