Crews cleared mud from key California highways as forecasters warned that more thunderstorms were on the way after downpours and high tides caused flooding, prompting road closures and rescues of people trapped in cars.

Heavy rain and high tides have caused flooding in parts of Northern California.

Flooding areas surrounding Deep Creek in St. Johns and Putnam counties will take time to drain due to astronomical high tides hinder quick runoff into the St. Johns River.

Friday marks the beginning of Florida's King Tides, a term that refers to the highest tides in any given period. King Tides, sometimes called Spring Tides, typically appear in the spring and fall. (Though the term "Spring Tides" refers to spring as in the action, not the season). "The King Tides adding a couple of feet to the water height is almost like the storm being a category higher on scale." Something like the King Tides could mean those who would typically see themselves as far enough away from the storm's threat could, in fact, be in danger.
