Flood­ing has knocked out pow­er to one Mis­souri polling site, made an­oth­er one hard to reach and closed dozens of roads in the state.

More than 7 inch­es of rain has fall­en in some ar­eas over the past two days. And the Na­tion­al Weath­er Ser­vice is­sued flood and flash flood warn­ings and watch­es across a large swath of the state, ex­tend­ing from its south­west cor­ner to the St. Louis area in the east.

The flood­ing left some dri­vers strand­ed in their ve­hi­cles and dis­rupt­ed bus ser­vice on mul­ti­ple routes in the St. Louis area.

In Jef­fer­son Coun­ty, just to the south of St. Louis, the sher­iff’s of­fice warned in a news re­lease that one polling site is not ac­ces­si­ble by many peo­ple be­cause of flood­ing.

In St. Louis Coun­ty, the weath­er flood­ed elec­tri­cal equip­ment in one sub­urb, knock­ing out pow­er to a church that is serv­ing as a polling place, the St. Louis Post-Dis­patch re­port­ed. Poll work­ers there are now run­ning the elec­tions us­ing a gen­er­a­tor.

De­spite the prob­lems, many vot­ers lined up in the rain to cast their bal­lots.
