ROMANS: Welcome back. All eyes on the Caribbean this morning tracking Tropical Storm Nate. It's already killed 20 people in Central America and prompted states of emergency along the Gulf Coast.</s>ROMANS: For the latest, let's bring in meteorologist Derek Van Dam.</s>DEREK VAN DAM, AMS METEOROLOGIST: Good morning, Dave and Christine. Unfortunately, I wish I had better news to report. Tropical Storm Nate has shown signs of organization and strengthening overnight. Current sustained winds, 45 miles per hour. Its center of circulation has just now moved off the shore of Honduras, into the warm ocean waters of the Caribbean Sea. It's got its eyes set on Yucatan Peninsula, tropical storm force winds, heavy rain, potential for flooding, Cozumel into Cancun. But after that, it's got its eyes set on the Gulf Coast states for late Saturday night and into the day on Sunday. That is why the National Hurricane Center has hoisted hurricane watches from Central Louisiana eastward, towards the border of Mississippi and Alabama with tropical storm watches for much of the Florida panhandle. We also have storm surge watches across much of Louisiana and into the Biloxi region. This includes Lake Pontchartrain and New Orleans and the additional rainfall that is expected across this region could bring localized flooding as well. Timeline again for the Yucatan Peninsula overnight on Friday. But as we look towards the Gulf Coast states, with the potential category one making landfall, that looks to be best chances late Saturday and into the day on Sunday.</s>ROMANS: All right. Derek, thank you for that. Investigators in Las Vegas looking into disturbing new details behind Sunday's mass shooting. He wanted tracer bullets. Can you imagine? We got more details next.
