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 12:00 PM to 11:59 PM PST.
IMPACTS Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible.
The barometric pressure readings for the high tides on this day are significantly higher than the threshold that has historically led to severe flooding events. The pressure readings of 1021.1 hPa and 1019.8 hPa during the high tides are well above the critical threshold of 992.8 hPa. Although the tide levels are not provided, the NOAA flood likelihood is low with a 0.0% chance, which suggests that the tide levels are not expected to reach the flood threshold of 2.1m. The wind direction is not specified, but given the low likelihood from NOAA and the high barometric pressure, it is unlikely that wind direction will play a significant role in increasing flood risk on this day.
CATEGORY 3
WHAT Minor coastal flooding potential remains due to elevated tide levels.
WHEN Highest risk during high tide times, particularly around 3:48 AM and 2:24 PM PST.
IMPACTS Similar minor impacts as Day 1, with potential for slightly increased water levels near shorelines.
On this day, the barometric pressure during high tides drops slightly compared to Day 1, with readings of 1015.1 hPa and 1012.7 hPa, which are still above the historical threshold for severe flooding events but indicate a trend towards lower pressures. The NOAA flood likelihood remains low at 0.0%, suggesting that while there may be an increased risk compared to Day 1 due to the lower pressures, it is still not expected to result in significant flooding without additional factors such as heavy rainfall or strong winds from critical directions.
CATEGORY 4
WHAT Elevated risk of coastal flooding due to further decreased barometric pressure and potentially higher tide levels.
WHEN Highest risk during high tide times, particularly around 4:12 AM and 3:18 PM PST.
IMPACTS Increased likelihood of flooding in low-lying areas and near shorelines with possible property damage.
The barometric pressure on this day drops significantly during high tides to readings of 1007.8 hPa and 1006.7 hPa, which are approaching the historical thresholds associated with more severe flooding events (Category 4). While NOAA's flood likelihood data remains low at a 0.0% chance, the proximity of these pressure readings to past Category 4 events suggests an increased risk of flooding compared to the previous days. The specific tide levels are not provided, but if they are elevated in conjunction with these lower pressures, there could be a greater impact than forecasted by NOAA's likelihood percentage.
Residents and businesses 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 heed any evacuation orders or safety instructions provided by emergency services.
