President trump, you see him here, touring damaged areas today. Thousands without power. Officials say it could take weeks to restore and weeks to rebuild. ABC's senior meteorologist rob Marciano is in Baton Rouge tonight. Reporter: Tonight, 500,000 customers still without power in the wake of hurricane Laura. Crews arriving, but face the daunting task of repairing or rebuilding the power grid. Tens of thousands also without running water in this stifling summer heat. Five out of six water plants in Lake Charles damaged. Water and electricity is out and you should expect it to be out for weeks. Reporter: The storm killing at least 16 people. More than half the deaths now linked to carbon monoxide poisoning from generators. Residents returning to find their homes decimated. Neighbors helping neighbors. When he knocked on that door, I was like, "Thank you god." Reporter: The convoy of hope, one of many volunteer organizations that have rolled into town with their donated supplies and handing them out to the storm victims that need it. Food, water, and tarps for damaged roofs. We found a woman who lost her home in the storm. What do you need? Water. Whatever they giving out. You be safe, all right? Reporter: Mercy chef's Gary leblanc makes restaurant-quality meals for those in need and if you can't pick it up, they'll deliver. To share a meal with someone who has just lost everything is a special honor for us. Such a tough time in Louisiana. Great to see relief getting in. Let's get to rob Marciano in Baton Rouge tonight. Rob, good evening. Reporter: Good evening, Tom. The weather has not been great for the first two days of recovery. Yesterday it rained. Today the heat was stifling. Heat advisories up for that part of the storm zone. Heat warnings up farther north. Temperatures around 111 degrees. That's what it feels like with the heat and humidity in Shreveport. Higher than that as you get into the Arkansas. Remnants of Laura in the northeast. Strong thunderstorms along I-95. D.C., philly, and New York, a tornado warning right now just north of Albany. That clears out tonight, and two more storm systems to watch as we mark today the 15th anniversary of hurricane Katrina, which we know devastated this part of Louisiana. Tom? 15 years ago.
