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 AM to 8:00 AM PST.
IMPACTS Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible.
The barometric pressure is relatively high at 1017 hPa, which is above the threshold that has historically indicated severe flooding events. However, the tide height at the time of high tide is significant, reaching levels that have previously been associated with minor flooding events. The NOAA flood likelihood for this day is low at 3.9%, which supports the prediction of a Category 3 event, indicating a situation that should be monitored but is unlikely to cause flood damage.
CATEGORY 5
WHAT Coastal flooding likely with potential for property damage. Inundation may exceed 1 foot above ground level in some areas near the shoreline and low-lying regions.
WHEN From 6:00 AM to 9:00 AM PST and again from 5:30 PM to 8:30 PM PST.
IMPACTS Moderate flooding of coastal areas, with some roads potentially becoming impassable. Property damage is possible, especially in vulnerable structures or those not elevated to account for such surge levels.
The barometric pressure is forecasted to be significantly lower on this day, at around 1002 hPa during the morning high tide and slightly higher at 1003 hPa during the evening high tide. These pressures are much closer to the thresholds observed during previous flooding events. Combined with high tide levels and a NOAA flood likelihood of high at 10.1%, there is a substantial risk of flooding that could lead to property damage, warranting a Category 5 prediction.
CATEGORY 3
WHAT Minor coastal flooding expected similar to Day 1. Possible inundation up to 0.5 feet above ground level near shorelines and low-lying areas.
WHEN From 6:00 AM to 9:00 AM PST and again from 7:00 PM to 10:00 PM PST.
IMPACTS Minor flooding of low-lying areas, parks, and roads with isolated road closures possible.
On this day, the barometric pressure is high again at around 1018 hPa for both high tides, which reduces the likelihood of severe weather conditions leading to significant flooding. The NOAA flood likelihood remains high at 7.9%, but given the pressure readings and comparison with historical data, it suggests that while there may be minor coastal flooding, it is not expected to cause major property damage or severe impacts, thus fitting a Category 3 prediction.
Residents and businesses near the shore 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.
