ST. LOUIS – Get ready for another round of severe storms. The latest system rolling through the St. Louis region could hit hard late Friday evening and pose risks overnight.

A severe thunderstorm watch is in effect for St. Louis City and many nearby counties as of 10 p.m. Friday evening. This is all in anticipation of a round of thunderstorms coming in from the west.

Impacts may begin around 11 p.m. Friday, but the biggest threats could come around midnight or shortly after that. There have been tornado warnings in some parts of Missouri. Lincoln, Montgomery and Pike counties in the northern part of FOX 2’s viewing area are also under a flood watch.

The National Weather Service says the upcoming storm system could generate speeds up to 70 mph, but the chance for tornado is low. Heavy rainfall and hail are also threats.

For a tornado, it means conditions are favorable for a tornado to form, but it has not yet been indicated by radar. If it’s upgraded to a tornado warning, radars have tracked a tornado, so seek shelter immediately.

As for a flood watch, it means conditions are favorable for flooding. If it’s upgraded to a flood warning, move immediately to higher ground and have some essential items on hand.

Rain, thunderstorm threats will continue overnight, but should dissipate early Saturday morning. Download the FOX 2 weather and news apps to stay up-to-date on developing conditions.
