00:45 Drought Relief for California? Meteorologist Ari Sarsalari talks about a system moving into the West Coast, that could bring rain to areas hard hit by drought.

Days of heavy rain in the Mediterranean region of southeastern France triggered flash floods and severe flooding that killed at least four people and left two missing, officials said.

According to weather.com meteorologist Linda Lam, the region has experienced rain off and on since Monday, with the heaviest rainfall on Thursday into Friday. For instance, more than 4 inches of rain has fallen on Hyères, France, so far this week; the area typically sees that much rain in a month, Lam said.

All of that rain has saturated the soil, leading to deadly flash flooding events and widespread river flooding.

In one such instance, a woman's body was found next to her vehicle near a flooded river in the French department of Var, the Associated Press reports. According to Var officials , the woman was traveling with her 8-year-old daughter, who remains missing.

"Her daughter has not been found. It is likely that the child has died," the official told the French edition of The Local.

Two other people were killed in Var, France, after being swept away by floodwaters. One woman's body was recovered on a beach in Hyères, France, and a man's body was recovered in Cogolin, France.

The Local reports that emergency personnel had to rescue 30 children from a school in Grimaud, France, after floodwaters rose high enough to trap the students. All the children were rescued safely, the site reports.

Unfortunately the rain and flood woes will only continue well into the weekend, according to Lam. As a result, a host of flood and heavy rain warnings were in place for the southernmost portions of France Friday.

Of particular concern was the Orb River in the department of Hérault. According to MeteoFrance, there was a"major flood risk" -- the most severe warning issued by the agency -- with a "direct and widespread threat to the security of persons and property" for the upstream portions of the Orb River in the department on Friday.

The French departments of Pyrenees-Orientales, Aude and Hérault, all had orange warnings -- the second most severe type of warning -- posted for potential flooding on Saturday, according to MeteoFrance.

Rain and flooding has plagued the south of France this year. In September and October, two major flash flooding events swept through Montpellier, France. The second event dumped more than 10 inches of rain, causing a torrent of floodwater to rush through the city and its soccer stadium, severely damaging the structure.
