An unfamiliar phone number is easy to ignore. Little Elm's emergency-notification guidance recommends saving the number its LEALERT system uses: 972-316-7027.

That existing resource is worth reviewing ahead of this week's heavy-rain threat. Little Elm Alerts can deliver time-sensitive information by phone, text and email, including severe-weather and road-closure notices. Residents can choose delivery methods through the town's official notification page.

Denton County is included in a National Weather Service flood watch scheduled from 4 p.m. Wednesday, Sept. 30, through 7 a.m. Friday, Oct. 2. All times are Central Daylight Time. The Fort Worth forecast office extended the watch in its 2:15 p.m. Sept. 29 update.

The alert projects 2 to 4 inches of rain across the watch area, with 4 to 6 inches in localized pockets. Slow-moving showers and storms could cause runoff that affects creeks, low-lying areas and low-water crossings.

The watch itself does not confirm a closure in Little Elm or a particular neighborhood's rainfall total. It means flooding is possible during the stated period, so residents should continue checking the Weather Service for later warnings and instructions.

Before driving, look for current local notices and be prepared to choose another route if water covers the road. Phone notifications are useful alongside official forecasts; they should not replace paying attention to barricades or hazardous conditions encountered on the trip.
