Details from Rochester emergency management:
A severe thunderstorm passed through Rochester around 10 am. NW/NE Rochester experienced heavy rain. Several manhole covers were lifted by water pressure, and some streets were damaged by heavy rainfall. Here is a snapshot of the current rainfall report on the Rochester Hydrology page.
It was a busy time for RFD engine companies, and to say Public Works street crews are busy is an understatement. The purpose of this update is about the future – what to expect from storms later today.
NWS La Crosse predicted several rounds of thunderstorms (true), with the greatest risk from evening thunderstorms. The prediction for later severe storms is “iffy”. It seems the morning thunderstorms sucked the energy from the atmosphere, and later storms might not be as bad. Of course, with all weather, time will tell. At this time, NWS does not think the evening storms will be as threatening. Any severe weather or heavy rainfall will arrive around 10 pm. There will be sporadic rain throughout the day, and heavy rainfall – if any – will be later tonight.
