Good morning, NBC News readers.
Still-recovering Puerto Ricans are on edge ahead of what may be another devastating storm, a royal twist in the Brexit saga and Saturday Night Live gets a cast shake-up.
Here's what we're watching today.
Tropical Storm Dorian strengthens, takes aim at Puerto Rico
Residents of the still-recovering Caribbean island are bracing for Dorian, which is expected to hit by Wednesday afternoon.
Puerto Rico is under a hurricane watch, as well as a tropical storm warning, and has declared a state of emergency.
"We’re scared. We know what may be coming," said San Juan Mayor Carmen Yulín Cruz.
Meanwhile the Trump administration is pulling $271 million in funding from FEMA disaster relief to pay for immigration detention space and temporary hearing locations for asylum-seekers on the southern border.

U.K. leader asks queen to suspend Parliament, prompting fury from Brexit opponents
The British government was accused of bringing the country to the brink of a constitutional crisis Wednesday as Prime Minister Boris Johnson asked the queen to temporarily suspend Parliament.
Opponents see the move as an extraordinary attempt to make it harder for lawmakers who want to thwart the prime minister's plans for Brexit, as the deadline for Britain to leave the European Union looms on Oct. 31.
Purdue Pharma offers $10-12 billion to settle opioid claims
The maker of OxyContin, Purdue Pharma, and its owners, the Sackler family, are offering to settle more than 2,000 lawsuits against the company for $10 billion to $12 billion.
The lawsuits brought by states, cities and counties allege that the company and the Sackler family are responsible for starting and sustaining the opioid crisis.
Purdue Pharma, which makes the opioid painkiller OxyContin, and the Sackler family have denied the allegations laid out in the lawsuits.
According to the proposed plan, the drug company would declare Chapter 11 bankruptcy in order to pay out the billions.
'A drop in the bucket': $20 million to help Brazil put out the Amazon fires won't go far
An offer from the world's richest nations to help Brazil stamp out the Amazon fires with $20 million in aid is a goodwill gesture, but it will barely make a dent in preventing further destruction of the rainforest's vast and intricate ecosystem, observers who have studied the region say.
"Twenty million dollars is a drop in the bucket," said Robert T. Walker, a University of Florida professor who has conducted environmental research in the Amazon for 25 years.
"It's absurd to imagine logistically what effect it can have."
