HEADING: Flood Watch

Redondo Beach, WA

DayInfo1: Day 1: 2024-10-29

CATEGORY 3

WHAT Minor coastal flooding is possible. Inundation of up to 1 foot above ground level near shorelines and low-lying areas may occur.

WHEN From 2:00 PM to 4:00 PM PST.

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

ADDITIONAL DETAILS...

On October 29, 2024, the high tide is expected at 2:54 PM with a tide height of approximately 18.84 feet, which is higher than the historical Category 3 event on 12/27/2023 (17.460 feet). However, the barometric pressure is forecasted to be around 1020.75 hPa, significantly higher than in previous severe flood events, indicating stable atmospheric conditions and a lower likelihood of severe weather-induced flooding.

Wind speeds are moderate at approximately 5 mph coming from the south (wind direction 172°), which is less impactful compared to higher-category historical events that featured stronger winds from directions that exacerbate flooding.

The NOAA High Tide Flooding Likelihood for this date is low, with a 0.0% chance of flooding and a distance to threshold of -2.33 meters, suggesting tides well below flood-triggering levels.

Based on the combination of higher barometric pressure, moderate wind conditions, and NOAA's low flood likelihood, the risk of significant flooding remains low but conditions should be monitored. This aligns with a Category 3 classification—close to a flood event and worth monitoring, but unlikely to cause flood damage.


DayInfo2: Day 2: 2024-10-30

CATEGORY 3

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

WHEN From 3:00 PM to 5:00 PM PST.

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

ADDITIONAL DETAILS...

On October 30, 2024, the high tide is expected at 3:12 PM with a tide height reaching approximately 18.78 feet, similar to Day 1. The barometric pressure is forecasted to be around 1018.10 hPa, slightly lower than the previous day but still significantly higher than pressures associated with historical severe flooding events.

Wind conditions show speeds around 6 mph from the southeast (wind direction between 135° and 164°). This wind direction is not typically associated with increased flood risk in Redondo Beach, WA.

NOAA's Flood Likelihood Analysis continues to indicate a low flood likelihood with a 0.0% chance and a distance to threshold of -2.40 meters, reflecting tides below critical levels.

Considering the stable barometric pressure, moderate tide heights, and low NOAA flood likelihood, the flood risk remains minimal, consistent with a Category 3 event. Monitoring is advised, but major flooding is unlikely.


DayInfo3: Day 3: 2024-10-31

CATEGORY 3

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

WHEN From 3:30 PM to 5:30 PM PST.

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

ADDITIONAL DETAILS...

On October 31, 2024, the high tide is expected at 3:30 PM with a tide height of approximately 18.69 feet, slightly lower than the previous two days. The barometric pressure is forecasted to be around 1015.51 hPa, which is lower than Days 1 and 2 but still well above the levels observed during historical severe flooding events (e.g., <= 1002 hPa in Category 4 events).

Wind speeds are anticipated to increase slightly to around 9 mph from the north-northeast (wind direction 15° to 21°). While higher than previous days, this wind speed remains moderate, and the wind direction does not significantly contribute to flood risk in this region.

The NOAA Flood Likelihood remains low, with a 0.0% chance of flooding and a distance to threshold of -2.59 meters, indicating tides safely below the flooding threshold.

Given the moderate tidal heights, decreased but still stable barometric pressure, and low flood likelihood from NOAA, the conditions align with a Category 3 classification. It is prudent to stay informed, but significant flooding is not expected.


PA: 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.
