Flood Watch in effect for Montgomery County on Monday, July 14

The National Weather Service has issued a Flood Watch for Montgomery County, in effect from Monday afternoon through Monday evening, July 14. With storms forecast to bring intense rainfall to the region, local officials are urging residents to prepare for the possibility of flash flooding, especially in flood-prone or low-lying areas.

Rain on Saturated Ground

Following a string of wet days, the ground across Montgomery County is already near saturation, increasing the likelihood of runoff and flooding even with moderate rainfall. Forecast models predict slow-moving thunderstorms throughout the afternoon and evening, with some capable of producing two to three inches of rain per hour.

"Given the current soil conditions and the potential rainfall rates, localized flooding is a real concern," the National Weather Service said in its advisory. “Creeks and small streams could rise rapidly.”

Areas of Concern

Montgomery County is particularly vulnerable to flooding, with FEMA ranking the area among the top flood-risk counties in the nation. Tributaries like the Schuylkill River, Neshaminy Creek, and other smaller streams pose significant risk when heavy rain occurs in short bursts.

Urban areas such as Norristown, Lansdale, and Pottstown are also susceptible, especially where storm drains are overwhelmed or where roads dip below grade level

Just last week, severe storms led to over 600 emergency calls, numerous downed trees, flooded intersections, and several water rescues across Montgomery County. That incident prompted a flash flood warning and highlighted how quickly weather conditions can escalate in the region.

What Residents Should Do

Emergency officials recommend taking the following precautions today:

• Stay informed: Monitor local news, NOAA Weather Radio, and the county’s ReadyMontco alert system for updates.
• Avoid flood zones: Don’t attempt to drive or walk through flooded roadways. Just six inches of moving water can knock over an adult, and a foot of water can sweep away most vehicles.
• Prepare your property: Clear gutters and storm drains, secure outdoor furniture, and move valuables to higher floors if you're in a flood-prone area.
• Keep an emergency kit: Include flashlights, batteries, water, first aid supplies, and copies of important documents.
• Check on neighbors: Especially elderly or disabled residents who may need help evacuating or preparing.

Looking Ahead

The Flood Watch remains in effect until late Monday night. While not all areas will experience flooding, conditions are ripe for rapidly developing flash floods, especially where thunderstorms persist or repeat over the same location.

Officials urge residents to use caution, prepare ahead of time, and follow all local advisories.
