Tornado watch issued

4 p.m. update: The National Weather Service issued a tornado watch for most of south-central Indiana until 10 p.m.

NWS meteorologist Andrew White said there's a risk for severe weather through Saturday evening, but a tornado touchdown is more likely to happen after 5 p.m. and south of Interstate 70.

"The main things we're concerned with across the central part of the state are lightning and gusty winds," White said. Thunderstorms are also still expected into early Sunday morning, he said, with another inch of rain still possible.

"We want to make sure everyone has a plan in place in case there is severe weather," White said. "Those in the watch areas should keep their eyes on any changes to the weather or forecast."

Several inches of rain expected

10 a.m.: You may need more than just an umbrella to combat storms that could last through next week. 

The National Weather Service in Indianapolis issued a flash flood watch on Saturday morning, which is in effect from 11 a.m. Saturday until 8 a.m. Sunday morning. The watch includes Marion County and each county that surrounds it. 

Thunderstorms are possible at any time throughout the day Saturday. The main threats from the thunderstorms will be flash flooding and damaging winds.

Joseph Nield, a meteorologist with the NWS in Indianapolis, said 1 to 3 inches of rain is possible through Sunday morning, with higher amounts likely in central and northern areas of Central Indiana. 

Rainfall levels could be different in different areas, Nield said, because thunderstorms are variable in nature. 

Lightning is also possible, and an isolated tornado "cannot be ruled out," NWS said. "Marginally severe hail" around 1 inch in diameter is also possible, Nield said. 

While storms are possible anytime, severe storms are more likely in the afternoon and evening Saturday. Flash flooding is more likely to happen in the afternoon or overnight, NWS said. 

Indianapolis weather:Here's how the rain is impacting events

Concerts across Indianapolis this weekend were postponed or canceled due to the forecast, and bands scheduled to play at the Holy Rosary Italian Street Festival were canceled.

The festival's Marian Procession was also canceled. Masses scheduled for 4 and 7 p.m. were scheduled to proceed.

Nield said areas in Central Indiana with poor drainage and areas near small creeks and streams are most prone to flooding. Urbanization poses a flooding risk, he added, as concrete and blacktop are impervious to water, which causes water to run off into nearby bodies of water.

"Flood waters are nothing to mess around with," Nield said. "They're just something to steer clear of all together."

The Federal Emergency Management Agency says when a Flash Flood Watch is issued, you should be prepared to move to higher ground on short notice. Here are some actions FEMA says you can take to stay safe:

• Monitor local weather reports.
• Consider how you will stay informed if there is a power outage. Think about having extra batteries for your battery-operated radio or cell phone, and consider having your cell phone charger on-hand. 
• Create an evacuation plan.

Storms could continue Sunday through Friday, NWS said. Strong storms are possible Sunday, and lightning is possible anytime through Friday. Repeated rainfall, if it occurs, could lead to moderate widespread flooding throughout the week.

Just because the Flash Flood Watch ends Sunday morning doesn't mean flash flooding after Sunday morning isn't possible, Nield said. Anywhere from 2 to 4 inches of rain is possible through Friday next week, he said.
