Day 2: 2024-09-14

CATEGORY 3

WHAT Moderate coastal flooding expected. Possible inundation of up to 2 feet above ground level near shorelines and low-lying areas.

WHEN From 12:00 AM to 03:00 PM PST.

IMPACTS Moderate flooding of low-lying areas, parks, and roads. Some road closures possible.

ADDITIONAL DETAILS...

On 2024-09-14, the high tide at 00:06 AM is expected to reach a height of approximately 16.813 feet with a barometric pressure of 1015.01 hPa. The second high tide at 15:12 PM will reach approximately 18.645 feet with a barometric pressure of 1013.51 hPa. The lower barometric pressure combined with higher tide heights increases the risk of moderate flooding, though it is still below the threshold for severe events seen in historical data.

Day 3: 2024-09-15

CATEGORY 4

WHAT Likely coastal flooding expected. Possible inundation of up to 3 feet above ground level near shorelines and low-lying areas.

WHEN From 12:00 AM to 03:00 PM PST.

IMPACTS Likely flooding of low-lying areas, parks, and roads. Road closures likely.

ADDITIONAL DETAILS...

On 2024-09-15, the high tide at 01:18 AM is expected to reach a height of approximately 17.310 feet with a barometric pressure of 1012.91 hPa. The second high tide at 15:36 PM will reach approximately 19.008 feet with a barometric pressure of 1009.25 hPa. The combination of lower barometric pressure and higher tide heights significantly increases the risk of coastal flooding, similar to historical Category 4 events.

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.


Forecast Reasoning:

Day 1 (2024-09-13):

  1. Barometric Pressure: High (1017 -1018 hPa)
  2. Tide Height: Moderate (10 -17 ft)
  3. Wind Direction: SSW (191°) with speeds around (5 kmph)
  4. NOAA Flood Likelihood: Low

Given these conditions, the flood potential is categorized as Category 2 due to moderate tide heights and high barometric pressure indicating less severe weather conditions.

Day 2 (2024-09-14):

  1. Barometric Pressure: Moderate (1013 -1015 hPa)
  2. Tide Height: High (16 -18 ft)
  3. Wind Direction: SSW (193°) with speeds around (5 kmph)
  4. NOAA Flood Likelihood: Low

The flood potential is categorized as Category 3 due to higher tide heights combined with moderate barometric pressure indicating an increased risk but not severe enough for major property damage.

Day 3 (2024-09-15):

  1. Barometric Pressure: Lower (1009 -1012 hPa)
  2. Tide Height: High (17 -19 ft)
  3. Wind Direction: SSW (193°) with speeds around (5 kmph)
  4. NOAA Flood Likelihood: Low

The flood potential is categorized as Category 4 due to lower barometric pressure combined with higher tide heights indicating a significant risk for coastal flooding similar to historical Category 4 events.
