Southbound lanes of I35 just north of Temple were closed due to flooding Thursday morning.

The lanes near FM 1237/Pendleton Road were rendered impassable by heavy rains that fell throughout the night. Access roads are open, but traffic is extremely slow and alternate routes are advised.

Northbound lanes that were closed early Thursday have reopened, but that may be temporary if the rain continues.

Drivers are advised to take it slow in these areas and turn off cruise control.
