Hurricane Joaquin combined with another low pressure system moving through is expected to bring as much as 10 inches of rain to some parts of Chatham County through Monday.
Residents and businesses are advised to prepare for periods of flash flooding.
A water main break occurred on South Second Avenue in front of Chatham Middle School.
Along with the school the affected areas are Dan Henry Siler Road and Autumn Drive.
Chatham County Water customers south of Siler City may also experience water loss owing to this water line break event.
When water systems lose pressure there is an increased risk of contamination. Therefore, if you live in an area that is impacted by this event, you are under a Boil Water Advisory.
