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 10:00 PM to 11:59 PM PST.

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

ADDITIONAL DETAILS...

The barometric pressure is forecasted to be above the threshold that historically indicates severe flooding, suggesting less severe weather conditions for this event. However, the high tide at 11:12 with a mean pressure MSL of 1001.989990234375 hPa and at 22:18 with a mean pressure MSL of 1003.260009765625 hPa, combined with the NOAA's low flood likelihood prediction, indicates a potential for minor coastal flooding. The wind direction is not provided but considering the historical data, unless it is from W/NW, it may not significantly impact the flood potential.

Day 2: 2024-07-29

CATEGORY 2

WHAT Coastal conditions expected to be stable with a very low chance of flooding.

WHEN Throughout the day.

IMPACTS No significant impacts expected. Normal tidal conditions likely to prevail without any substantial overflow.

ADDITIONAL DETAILS...

The barometric pressure readings for the high tides on this day are slightly lower than on Day 1, with readings of 1001.0800170898438 hPa and 1000.6099853515625 hPa. However, NOAA's Flood Likelihood Analysis indicates a low likelihood of flooding with no expected deviation from the flood threshold. The absence of significant rainfall or extremely low barometric pressure readings suggests a stable day with respect to flood risk.

Day 3: 2024-07-30

CATEGORY 4

WHAT Elevated risk of coastal flooding due to high tide and lower barometric pressure.

WHEN Highest risk near the morning high tide from 8:00 AM to 10:00 AM PST.

IMPACTS Potential for moderate flooding of coastal areas, including roads and properties close to the shoreline. Residents should be prepared for possible evacuation if advised by local authorities.

ADDITIONAL DETAILS...

On this day, the barometric pressure during high tide drops closer to the threshold that has historically indicated more severe flooding events (998.1599731445312 hPa). The tide height is also expected to be relatively high, although specific values are not provided. Given these factors and comparing them with historical events, there is an elevated risk for coastal flooding that could potentially cause property damage if combined with adverse weather conditions or wind directions from W/NW.

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 evacuation orders or safety instructions provided by emergency services.
