Redondo Beach, WA
CATEGORY 3
WHAT Minor coastal flooding expected. Possible inundation of up to 0.5 feet above ground level near shorelines and low-lying areas.
*WHEN From 5:00 PM to 7:00 PM PST.
IMPACTS Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible.
The barometric pressure is forecasted to be around 998.7 hPa during the high tide at 6:12 PM, which is higher than the threshold that historically indicates severe flooding risk. However, the tide height is not expected to exceed the critical mark of 21 feet, as seen in past Category 4 or higher events. The NOAA Flood Likelihood Analysis indicates a low likelihood of flooding for this day, with a distance to threshold of -1.77m from the flood threshold of 2.1m. Wind direction data is not provided, but historical events suggest that winds from the W/NW could contribute to flood risks. Comparing with historical data, especially the event on 12/17/2022, the potential for high-tide flooding risks remains moderate but warrants close monitoring due to the combination of high tide and lower-than-average barometric pressure.
CATEGORY 2
WHAT Coastal conditions expected to be mostly stable with a very low chance of minor tidal overflow.
WHEN The risk period is minimal throughout the day due to favorable conditions.
IMPACTS No significant impacts expected. Standard caution advised for typically vulnerable areas during high tide.
The barometric pressure is slightly lower than on Day 1, around 997.4 hPa during early morning high tide at 4:24 AM, but still not indicative of severe weather conditions that could lead to flooding. The NOAA Flood Likelihood Analysis maintains a low likelihood for this day as well, with a distance to threshold of -1.95m from the flood threshold of 2.1m. Without significant wind data or other exacerbating weather conditions, the risk remains low for any substantial flooding events.
CATEGORY 1
WHAT No risk of coastal flooding; conditions are expected to be calm with no significant tidal impact.
WHEN Throughout the day, tidal levels are expected to remain within normal ranges without any notable risk periods.
IMPACTS No impacts from tides are anticipated; regular daily activities can proceed without interruption from tidal events.
On Day 3, barometric pressure readings are forecasted to be above 1000 hPa during both high tides, which significantly reduces the likelihood of flooding when compared with historical data points that indicate increased risk at lower pressures. The NOAA Flood Likelihood Analysis supports this assessment with a low likelihood percentage and a substantial distance from the flood threshold. Given these factors and barring any unforeseen weather changes, there is no anticipated risk for flooding based on current predictions.
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. Always follow local authority guidance and never drive through flooded roadways. Stay informed on the latest weather updates as conditions can change rapidly.
