Water levels in the Anclote River in Elfers and Cypress Creek in Wesley Chapel have triggered a warning from the National Weather Service.
Both bodies of water have risen to minor flood stage.
According to the weather service, the Anclote River in Elfers near Little Road and River Oaks Court, crested at 21.99 feet Thursday afternoon, just shy of moderate flood stage. Flood stage in that area is considered 20 feet.
Meanwhile, Cypress Creek, in the Worthington Gardens area south of State Road 56 and near Alvarez Acres, crested at 9.8 feet Thursday. Flood stage is 9 feet.
"If (residents) are experiencing flooding, obviously the Pasco County Health Department doesn't recommend that they stay within standing water if they happen to experience that," Pasco County spokesman Eric Keaton said. "Everyone is going to have a different experience."
Residents who have questions should call the county's resident information line at (727) 847-8959.
The Anclote is projected to continue dropping and should dip below 15 feet by Saturday.
Cypress Creek should drop, according to National Oceanic Atmospheric Administration projections, to about the 8-foot mark by Saturday.

Debby dumped nearly 15 inches of rain on Pasco County, mainly in the western portions of the region, at the end of June. That rainfall overflowed the Anclote and Pithlachascotee rivers. The flooding affected more than 7,000 residents and left one person dead.
The body of David Glenn Huntley, 46, was found in the Anclote River just off Celtic Drive on June 28.
