Hurricane Sally lands on the same spot as Alabama's last hurricane 16 数年前

Hurricane Sally made landfall Wednesday morning, 丁度 16 years to the day and almost to the hour when Hurricane Ivan made landfall in 2004.

More interestingly, they not only share a landfall date, but also the exact landfall location; Gulf Shores, アラバマ.
実際には, both Ivan and Sally’s landfall location and timing were eerily similar.
Their distances were only about 15 miles apart, and both made landfall early in the morning only about 3 hours apartIvan at 3 午前. and Sally shortly before 6 午前.
    Ivan was a bit stronger, making landfall as a Category 3 storm with sustained winds of 120 mph. Sally made landfall as a Category 2 storm with sustained winds of 105 mph.

    The tracks of the storm are also very similar

    After landfall, the tracks of the storms also bear very close similarities.
    Sally is expected to slowly push through Georgia and the Carolinas before tracking into the Atlantic Ocean.
    Ivan’s track was slightly west and north of Sally, but still impacted many of the same states: アラバマ, ジョージア, サウスカロライナ, and North Carolina (in addition to Tennessee and Virginia).
    そこから, Ivan’s track gets a little crazy.
    Ivan pushed out into the Atlantic Ocean before diving south and crossing back over southern Florida and into the Gulf of Mexico.
    最後に, Ivan made another landfall near Cameron, Louisiana as a tropical depression on September 23.
    今のところ, Sally’s track just has the storm going out into the Atlantic Ocean this Friday as a post-tropical depression, prior to dissipating.

    There is one difference thougNS

    One difference between the two hurricanes is the speed.
    For about three days, Sally barely moved faster than a turtle.
    At landfall, Sally was only moving at 2 mph; sea turtles as well as the average human walk at around 3-4 mph.
    Ivan, しかしながら, was much faster with a landfall speed of around 13 mph.
    That forward speed is important in terms of rainfall, as Sally was able to dump a significant amount more rain across some areas due the hurricane’s slow forward movement.

    The risk of tornadoes from each hurricane

    With Ivan there were 29 tornado reports the day before landfall, 23 tornado reports on landfall day, そして 59 tornado reports the day after across five states.
    A grand total of 111 tornado reports were tallied in just three days across eight states: フロリダ, ジョージア, サウスカロライナ, ノースカロライナ州, バージニア, メリーランド, ペンシルベニア, and West Virginia.
    There is a slight risk (level two out of five) for tornadoes Wednesday in Florida, アラバマ, and Georgia from Sally.
    Hurricanes and tropical storms that make landfall in the Gulf of Mexico are more likely to produce tornadoes compared to storms in the Atlantic,” explains Brandon Miller, CNN meteorologist.

      Note that this is less true for Texas landfalls in the Gulfsince the coastline angles more south to north like the Atlantic East Coast, rather than east to west like in the northern Gulf of Mexico coastline of Louisiana, ミシシッピ, アラバマ, フロリダパンハンドル,” ミラーは言った.
      言い換えると, a tropical system that landfalls in Alabama, like Sally, could produce a few more tornadoes than a landfall in say, Galveston, テキサス.
