The new policy restricts immigrant visas for citizens of Nigeria, Sudan, Tanzania, Eritrea, Myanmar, and Kyrgyzstan. It does not ban them from traveling to the U.S. for other reasons.

While conditions improved slightly over the weekend, forecasters warn that dangerously hot and windy conditions will likely return later this week.

The Bahamas' government is sharing a wish list of materials to help the country provide food and shelter for residents who are still reeling from Hurricane Dorian. Officials say they need lots of help and supplies — but they also want targeted donations.

"Officials here for instance don't want to be inundated with cans of green beans when what they really need is telephone poles," NPR's Jason Beaubien reports from the capital city, Nassau.

They're facing a relief and reconstruction job that's likely to go on for years.

Jacobs delivered a keynote speech Tuesday at the National Weather Association's annual meeting in Huntsville, Ala. He defended a National Oceanic and Atmospheric Administration statement issued Friday that was widely seen as backing the president, but he also expressed support for the National Weather Service and its forecasters.
