Flood Watch

Redondo Beach, WA

Day 1: 2024-08-19

CATEGORY 2

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

*WHEN From 03:00 AM to 05:00 AM PST and from 05:00 PM to 07:00 PM PST.

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

ADDITIONAL DETAILS...

On August 19, the high tide at 03:12 AM is expected to reach a height of approximately 18.504 feet with a barometric pressure of 1016.36 hPa. The second high tide at 05:24 PM will reach around 19.597 feet with a barometric pressure of 1018.15 hPa. Both events are accompanied by relatively high barometric pressures, which historically indicate a lower risk of severe flooding. Wind speeds are low, ranging from 2 to 10 mph, and wind directions are not significantly contributing to flood risk.

Day 2: 2024-08-20

CATEGORY 3

WHAT Moderate coastal flooding expected. Possible inundation of up to 2 feet above ground level near shorelines and low-lying areas.

WHEN From 04:00 AM to 06:00 AM PST and from 06:00 PM to 08:00 PM PST.

IMPACTS Moderate flooding of low-lying areas, parks, and roads. Some road closures possible.

ADDITIONAL DETAILS...

On August 20, the high tide at 04:06 AM is expected to reach a height of approximately 18.703 feet with a barometric pressure of 1017.19 hPa. The second high tide at 05:54 PM will reach around 19.860 feet with a barometric pressure of 1012.58 hPa. The evening high tide is particularly concerning due to the lower barometric pressure, which increases the likelihood of moderate flooding. Wind speeds are slightly higher than the previous day but still moderate, ranging from 5 to 14 mph, with wind directions that do not significantly exacerbate flood risk.

Day 3: 2024-08-21

CATEGORY 4

WHAT Significant coastal flooding expected. Possible inundation of up to 3 feet above ground level near shorelines and low-lying areas.

WHEN From 05:00 AM to 07:00 AM PST and from 07:00 PM to 09:00 PM PST.

IMPACTS Significant flooding of low-lying areas, parks, and roads. Road closures likely, potential property damage in vulnerable areas.

ADDITIONAL DETAILS...

On August 21, the high tide at 05:06 AM is expected to reach a height of approximately 18.677 feet with a barometric pressure of 1008.27 hPa. The second high tide at 06:24 PM will reach around 20.074 feet with a barometric pressure of only 1007.66 hPa. The combination of high tide heights and lower barometric pressures significantly increases the risk of substantial coastal flooding on this day. Wind speeds are moderate but consistent, ranging from 4 to 10 mph, with wind directions that could contribute slightly to the flood risk.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

You 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.


Forecast Reasoning:

DayInfo1:

DayInfo2:

DayInfo3:

The analysis indicates increasing flood risks over the three days due to decreasing barometric pressures combined with rising tide heights, particularly on August 21st when significant coastal flooding is likely.


Please consult local authorities or experts for final decision-making in flood-related situations as this analysis is based solely on provided data and does not include other potentially relevant factors like hydrodynamic data or ground saturation levels.
