Redondo Beach, WA
CATEGORY 4
WHAT Moderate coastal flooding expected. Possible inundation of up to 1-2 feet above ground level near shorelines and low-lying areas.
*WHEN From 5:00 AM to 7:00 PM PST.
IMPACTS Moderate flooding of low-lying areas, parks, and roads. Isolated road closures possible, with some properties at risk of inundation.
The barometric pressure is forecasted to be significantly lower than the threshold of 992.8 hPa, which is a strong indicator of potential flooding. The high tide at 05:36 is expected to be accompanied by a mean pressure MSL of 998.9500122070312 hPa, which is close to the threshold and could contribute to flooding risks. The second high tide at 18:42 with a mean pressure MSL of 988.9400024414062 hPa is particularly concerning as it falls below the critical threshold, increasing the likelihood of significant flooding. This situation is somewhat similar to the Category 3 event on 12/27/2023 but with a lower barometric pressure, suggesting a higher risk. The NOAA Flood Likelihood Analysis indicates a low likelihood for this date; however, the combination of low pressure and high tide suggests a more cautious approach is warranted.
CATEGORY 3
WHAT Elevated risk of minor coastal flooding. Potential for water levels to reach up to 1 foot above ground in some shorelines and low-lying areas.
WHEN From 5:30 AM to 8:00 PM PST.
IMPACTS Minor flooding in susceptible areas, with possible impacts on parking lots, parks, and immediate coastal areas. Low risk for property damage.
The barometric pressure remains low at around 990 hPa during both high tides, which could contribute to an increased risk of minor flooding. The tide heights are not as extreme as those seen in Category 4 or higher events from historical data, but they are still significant enough to warrant attention. The NOAA Flood Likelihood Analysis maintains a low likelihood for this date, aligning with the forecasted conditions that suggest a lower severity compared to Day 1.
CATEGORY 2
WHAT Low risk of coastal flooding. No significant inundation expected but some pooling of water possible in low-lying areas.
WHEN Throughout the day, with attention to usual high tide times.
IMPACTS Minimal impacts anticipated. Some standing water may occur in typical trouble spots during high tide but should not affect property or infrastructure.
The barometric pressure on this day is higher than on previous days, around 995 hPa during both high tides, which reduces the likelihood of flooding compared to Days 1 and 2. The NOAA Flood Likelihood Analysis also indicates a low likelihood for this date, supporting the assessment that there is minimal risk for flooding. Historical data suggests that such pressure readings are not typically associated with significant flood events in this region.
Residents and businesses near the shore should monitor forecasts and be alert for possible Flood Warnings. Those living in areas prone to flooding should be prepared to take action should conditions worsen. Stay informed through local news and weather updates, and always follow instructions from local authorities regarding evacuations or safety measures.
