Weather in Michigan is warm right now!
but by October it will start to get cold.
If you have no winter clothes like a jacket mitten/gloves scarf
and hat the smaller items can be purchased
new the jacket can be gotten at a second-hand store for much cheaper than new especially
if Pannaporn won't be needing it back home.
Someone will pick her up. Her host family will do that do they have the information?
Last winter was very cold and snowy boots were necessary to track through the snow.
These can also be bought after she arrives there are stores for shoes and boots that are not too expensive.
Her host family can help he find these stores.
Sweaters/or sweat shirts are what the kids here where in the winter under their coats to keep them warm.
It will warm up again in April for sure.
