Redondo Beach, WA
CATEGORY 2
WHAT Minor coastal flooding expected. Possible inundation of up to 0.5 feet above ground level near shorelines and low-lying areas.
WHEN From 10:00 PM to 11:59 PM PST.
IMPACTS Minor flooding of low-lying areas, parks, and roads. Isolated road closures possible.
The barometric pressure is significantly higher than the threshold associated with previous flood events, indicating less severe weather conditions and a lower likelihood of an extreme flooding event. The high tide at 23:24 with a mean pressure MSL of 1020.1300048828125 hPa is not near the critical threshold of 992.8 hPa that would indicate a higher risk of flooding. The NOAA Flood Likelihood Analysis reports a low likelihood of flooding for this date, with a flood threshold distance of -2.13m, which supports the forecast of a Category 2 event.
CATEGORY 3
WHAT Elevated risk of coastal flooding. Potential for water levels to reach up to 1 foot above ground in some areas.
WHEN Highest risk during the morning high tide from 9:00 AM to 10:30 AM PST and again in the late afternoon from 4:00 PM to 6:00 PM PST.
IMPACTS Increased flooding of low-lying coastal areas and roads, with possible property damage in the most vulnerable locations.
The barometric pressure during the high tides is lower than on Day 1 but still above the critical threshold, with readings around 1011 hPa. However, the NOAA Flood Likelihood Analysis maintains a low likelihood for this date. The wind direction is not provided but considering the historical data, unless there are strong winds from W/NW, the risk remains moderate. The forecast is for a Category 3 event due to slightly lower pressures during high tides and the need for caution in vulnerable areas.
CATEGORY 2
WHAT Minor coastal flooding possible with water levels slightly above normal high tide marks.
WHEN Potential minor flooding around the time of high tide, particularly in the evening from 5:00 PM to 7:00 PM PST.
IMPACTS Low-lying coastal paths and roads may experience minor flooding. No significant property damage expected.
On Day 3, there are no high tides reaching the critical levels seen in historical flood events. The barometric pressure remains well above the threshold that would indicate severe weather conditions conducive to flooding. NOAA's Flood Likelihood Analysis indicates a low likelihood of flooding with a significant distance to the flood threshold. Therefore, the forecast remains at a Category 2 event with only minor impacts expected.
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. Consult local authorities or experts for final decision-making in flood-related situations and adhere to any advisories or evacuation orders that may be issued.
