Flood Watch

Redondo Beach, WA

Day 1: 2024-11-13

CATEGORY 3

WHAT Minor coastal flooding possible. Tide levels may approach thresholds that have previously led to minor flooding in low-lying areas.

WHEN From 1:00 PM to 3:00 PM PST.

IMPACTS Minor flooding of low-lying areas, parks, and roads near the shoreline. Isolated road closures possible.

ADDITIONAL DETAILS...

Barometric Pressure: The barometric pressure during the high tide on November 13 at 2:06 PM is approximately 1015.95 hPa, which is significantly higher than pressures observed during historical flooding events (e.g., 1006.1 hPa during a Category 3 event on 12/27/2023). High barometric pressure suggests less severe weather conditions.

Tide Height: The predicted tide height peaks at approximately 20.217 ft at 2:06 PM. This is higher than the tide height during the historical Category 3 event (17.460 ft) but lower than Category 4 events, which had tide heights over 21 ft.

Wind Direction and Speed: Winds are expected to be from the south-southeast at around 15 km/h (9 mph) during the high tide period, which is lower than wind speeds observed during higher-category historical events (e.g., 23.3 mph during a Category 4 event).

NOAA Flood Likelihood: NOAA's forecast indicates a low flood likelihood of 1.4%, with a distance to the flood threshold of -0.95 m, suggesting that water levels are expected to remain below critical thresholds.

Based on these factors, minor coastal flooding is possible in low-lying areas, but significant property damage is unlikely.


Day 2: 2024-11-14

CATEGORY 3

WHAT Minor coastal flooding possible. Tide levels may approach thresholds that have previously led to minor flooding in low-lying areas.

WHEN From 1:30 PM to 3:30 PM PST.

IMPACTS Minor flooding of low-lying areas, parks, and roads near the shoreline. Isolated road closures possible.

ADDITIONAL DETAILS...

Barometric Pressure: The barometric pressure during the high tide on November 14 at 2:42 PM is approximately 1024.78 hPa, which is significantly higher than pressures observed during historical flood events. This high pressure indicates stable atmospheric conditions.

Tide Height: The predicted tide height peaks at approximately 20.324 ft at 2:42 PM, similar to Day 1 and still below the levels observed during Category 4 events.

Wind Direction and Speed: Winds are expected to be from the south-southwest at around 15 km/h (9 mph) during the high tide period. This is less intense than wind conditions during historical flooding events.

NOAA Flood Likelihood: NOAA's forecast indicates a low flood likelihood of 1.7%, with a distance to the flood threshold of -0.91 m.

Given these conditions, while minor flooding in low-lying areas is possible, significant flooding is unlikely.


Day 3: 2024-11-15

CATEGORY 3

WHAT Minor coastal flooding possible. Tide levels may approach thresholds that have previously led to minor flooding in low-lying areas.

WHEN From 2:00 PM to 4:00 PM PST.

IMPACTS Minor flooding of low-lying areas, parks, and roads near the shoreline. Isolated road closures possible.

ADDITIONAL DETAILS...

Barometric Pressure: The barometric pressure during the high tide on November 15 at 3:12 PM is approximately 1014.79 hPa, which remains higher than pressures associated with significant historical flood events.

Tide Height: The predicted tide height peaks at approximately 20.258 ft at 3:12 PM, consistent with the previous days and below the critical thresholds of historical higher-category events.

Wind Direction and Speed: Winds are expected to be light, coming from the north-northeast at around 4 km/h (2 mph) during the high tide period, indicating minimal wind impact on tidal levels.

NOAA Flood Likelihood: NOAA's forecast indicates a low flood likelihood of 1.6%, with a distance to the flood threshold of -0.94 m.

The combination of these factors suggests that while minor flooding is possible, the risk of significant flood-related impacts remains low.


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.
