I have never seen a website as you described. If a local amateur radio public service club that keeps its website up to date, perhaps there is an events page. I think your most efficient approach would be to contact your county's OEM that supervises the county RACES-ARES organization. If you don't want to join RACES-ARES, you could at least listen to their regularly scheduled nets. HTH.
