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 Gulf — since 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.
