HEADING: Flood Watch

Redondo Beach, WA

DayInfo1: Day 1: 2024-11-24

CATEGORY 2

WHAT No risk of flooding is expected.

WHEN Throughout the day.

IMPACTS No significant impacts anticipated.

ADDITIONAL DETAILS...

The barometric pressure on Day 1 is around 1012 hPa, significantly higher than pressures observed during historical flooding events (e.g., Category 3 event at 1006.1 hPa). The maximum tide height reaches approximately 19.175 ft at midday, which is below the levels associated with significant flooding in the past. Wind speeds are low, around 2 mph, with a southerly wind direction (winddirDegree: 160-211), which does not historically contribute to increased flooding risk. NOAA's flood likelihood for this date is low at 0.0%, with a distance to the flood threshold of -1.98 meters. Comparing these conditions to the historical Category 1 event on 03/02/2024, which had a lower tide height of 10.43 ft and higher pressure of 992.1 hPa, further supports the assessment of no flood risk for Day 1.


DayInfo2: Day 2: 2024-11-25

CATEGORY 2

WHAT No risk of flooding is expected.

WHEN Throughout the day.

IMPACTS No significant impacts anticipated.

ADDITIONAL DETAILS...

On Day 2, the barometric pressure remains high, around 1014 hPa during the peak tide times, which is substantially higher than pressures during historical flooding events. The maximum tide height is approximately 19.149 ft at 12:54 PM, higher than the Category 3 historical event but still below the thresholds of Category 4 events, which had tide heights over 21 ft. Wind speeds are minimal, ranging from 2 to 4 mph, with wind directions varying from north to northwest (winddirDegree: 352 to 304), which are not known to exacerbate flooding in this region. NOAA's flood likelihood remains low at 0.0%, with a distance to the flood threshold of -2.05 meters. Given these factors and the absence of severe weather conditions, the risk of flooding on Day 2 is minimal.


DayInfo3: Day 3: 2024-11-26

CATEGORY 3

WHAT Close to a flood event and worth monitoring, but unlikely to cause flood damage.

WHEN During the high tide period around 1:18 PM.

IMPACTS Minor impacts such as localized pooling of water in low-lying areas may occur, but significant flooding is not expected.

ADDITIONAL DETAILS...

Day 3 shows a decrease in barometric pressure to approximately 1006.37 hPa at the time of the high tide, which is comparable to the pressure observed during the historical Category 3 event on 12/27/2023 (1006.1 hPa). The tide height at 1:18 PM is around 19.025 ft, higher than the historical Category 3 event tide of 17.460 ft but still below the tide heights observed in Category 4 events (over 21 ft). Wind speeds are low, about 4 mph, with a northerly wind direction (winddirDegree: 352 to 7), which historically has not significantly contributed to flooding risk. NOAA's flood likelihood remains low at 0.0%, with a distance to the flood threshold of -2.18 meters. While the combination of lower barometric pressure and higher tide height suggests conditions close to a flood event, the absence of other exacerbating factors indicates that significant flooding is unlikely. Therefore, Day 3 is categorized as Category 3, warranting monitoring but not immediate concern.


PA: PRECAUTIONARY/PREPAREDNESS ACTIONS...

You 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.
