It sounds like he is in a really tough situation and needs some help. You can start by finding a warm, dry place that he can stay in until the storm passes.
If you know of any shelters in the area, they would be a great option. You can also provide him with warm clothing and blankets if you are able.
If there is no one around to help, you can check in on him from a distance and make sure he is safe and warm.
Be sure to stay in contact and check in on him until he is in a safe place.
