Round 1 Hurricane Florence, Round 2- Hurricane Dorian.. Stay and fight or run to safety? Please think about running to a shelter.


Hurricane Dorian on Wednesday 1026 PM EST (NOAA Satellite-geocolor)

This evening Hurricane Dorian is bearing down on South Carolina and North Carolina.  A little more than a year ago, it was Hurricane Florence.   

Hurricane Florence on September 11, 3 days before striking North Carolina

Comparisons in Hurricanes :  

Hurricane Florence -
Incredible damage in North Carolina and South Carolina from surge, flooding.
Highest winds 150 mph 
Lowest Pressure 937 millibars 
Landfall category 1

Hurricane Dorian -  
Highest winds 185 mph
Lowest Pressure 910 mb
Potential US landfall (Cat 2-3)
Massive damage in the Bahamas


Hurricane Florence caused tremendous amounts of flooding in North Carolina.  The storm surge went up the rivers causing flooding, the beaches and areas near the coastlines were devastated and heavy rains caused lots of flooding.

September 2018, Carolina road washed out near Wilmington 
Far away from the coast in Duplin Country, the Cape Fear River went over its banks causing a tremendous amount of damage.  House after house experienced flooding in a county where people are not rich.

In my opinion, Hurricane Dorian poses a greater risk than Florence.  First, it has been strengthening all day as has been upgraded to a Category 3.  It is also a big storm and reminds me of Hurricane Floyd.    Many people have not evacuated because earlier today it was forecasted to be a Category 1.  The models have been in disagreement with the satellite data, with the storm showing greater organization throughout the day.   I call family in NC and told them to be ready and that this might be worst than last year.    With Hurricane Florence, many people had a false sense of security because the storm was downgraded.  You have to look at all of the hazards (flooding, surge...)  and not just the winds.. 

Here are the things to bear in mind with Dorian if you live in Southeastern North Carolina or NE South Carolina.  

Winds -- they will likely gust beyond hurricane force for a large part of the region from Thursday through Friday.  Expect down trees and roof damage.  

Rain.. Flash flooding is likely in many areas

River flooding from Storm Surge.  If you live near the Cape Fear river, please consider staying in a shelter until Saturday.  The river will reach FLOOD stage.   I-40 was closed at Burgaw last year because the road was flooded.

Given that Round 2 is about to start  FOCUS and make sure that 

1. You have all of your electronics charged.
2. Make sure that you have gas.
3. Know where the local shelters are located.
4. Make sure that you have fresh water and foods for several days.
5.  Touch base with all loved ones before tomorrow morning and let them know where you would go if you have to evacuate. 
6. Get all of your prescriptions and important papers together and put them in a bag that you can take with you if you have to flee.
7.  Don't drive across a flooded road.
8.  Watch out for falling trees, debris, and electrical wires.
9.  Make sure that you have cash... 
10.  If you live near the Cape Fear River or others... It may flood anytime over the next 1-3 days.  Don't get lulled into thinking that it won't flood.  Dorian's storm surge is going to push the water into North Carolina.
11.  Trust your gut, if you don't feel secure, flee to a nearby shelter.

          previous assessment.
        - PLAN: Plan for life-threatening wind of equivalent CAT 1 or
          2 hurricane force due to possible forecast changes in
          track, size, or intensity.
        - PREPARE: Remaining efforts to protect life and property
          should be urgently completed. Prepare for considerable wind
          damage.
        - ACT: Move to safe shelter before the wind becomes hazardous.

    - POTENTIAL IMPACTS: Extensive
        - Some structural damage is likely, with buildings receiving
          roof damage as well as window, door, and garage door
          failures. Mobile homes potentially suffering severe damage,
          with some destroyed. Damage may be enhanced by projectiles.
          Locations may be inaccessible or uninhabitable for some
          time after the storm passes.
        - Widespread large limbs will be down and many trees snapped
          or uprooted, along with fences and roadway signs blown over.
        - Roads will be blocked in many areas as a result of large
          debris, especially within urban or heavily wooded areas.
          Several bridges, causeways, and elevated roadways will
          likely become unsafe.
        - Widespread areas will suffer from power and communication
          outages.
        - Several poorly secured small craft may break from their
          moorings.

          above ground somewhere within surge prone areas
        - Window of concern: through early Friday evening

    - POTENTIAL THREAT TO LIFE AND PROPERTY: Potential for storm
      surge flooding greater than 1 foot above ground
        - The storm surge threat has increased from the previous
          assessment.
        - PLAN: Shelter against storm surge flooding greater than 1
          foot above ground.
        - PREPARE: All flood preparations should be complete. Expect
          flooding of low-lying roads and property.
        - ACT: Stay away from storm surge prone areas. Continue to
          follow the instructions of local officials.

    - POTENTIAL IMPACTS: Unfolding
        - Potential impacts from the main surge event are unfolding.

* FLOODING RAIN
    - LATEST LOCAL FORECAST: Flash Flood Watch is in effect
        - Peak Rainfall Amounts: Additional 6-10 inches, with locally

    - POTENTIAL THREAT TO LIFE AND PROPERTY: Potential for major
      flooding rain
        - The flooding rain threat has remained nearly steady from
          the previous assessment.
        - PLAN: Emergency plans should include the potential for
          major flooding from heavy rain. Evacuations and rescues are
          likely.
        - PREPARE: Strongly consider protective actions, especially
          if you are in an area vulnerable to flooding.
        - ACT: Heed any flood watches and warnings. Failure to take
          action will likely result in serious injury or loss of life.

    - POTENTIAL IMPACTS: Extensive
        - Major flooding from rainfall may prompt evacuations and
          numerous rescues.
        - Rivers and streams may rapidly overflow their banks in
          multiple places. Creeks and ditches will flood and may
          contain strong currents.
        - Flood waters may enter many structures, and some may become
          uninhabitable. Some road scours or complete road failures
          will be possible, along with the potential for sinkholes.
          Many streets and parking lots may flood, and may be
          impacted by flowing water. Many road and low-lying bridge
          closures are possible with some weakened or washed away.
          Driving conditions will be dangerous.The delivery of
          drinking water and sewer services may be interrupted. Flood
          waters may be polluted and contain hazardous materials.

          few tornadoes.
        - PREPARE: If your shelter is particularly vulnerable to
          tornadoes, prepare to relocate to safe shelter before
          hazardous weather arrives.
        - ACT: If a tornado warning is issued, be ready to shelter
          quickly.

    - POTENTIAL IMPACTS: Limited
        - The occurrence of isolated tornadoes can hinder the
          execution of emergency plans during tropical events.
        - A few places may experience tornado damage, along with
          power and communications disruptions.
        - Tornadoes can cause damage to trees, vehicles, boats, and
          buildings. Unsecured mobile homes and poorly constructed
          structures are particularly vulnerable.
