Los Angeles got just a half-inch of rain this month, indicating that the city was experiencing the driest rain year on record, the National Weather Service reported Sunday.

The .05 inches that fell in March is more than 3 inches below the average March rainfall of 3.14 inches.

This rain season, which begins in July, is currently the driest downtown since records began to be kept in 1877, according to the Weather Service.

This was largely due to global warming which pushes up temperatures and leads to rising sea levels, said scientists.

Since July 1, downtown has received just 2.47 inches of rain --nearly a foot, or 11.47 inches below the normal precipitation to date, which is 13.94 inches.

To date, only 18 percent of normal rainfall has fallen. If downtown receives less than 1.95 inches of rain through June 30, it will become the driest rain season ever for the area, beating the 4.42 inches of rain that fell in 2001-02.

Average rainfall begins to drop off sharply in Los Angeles in April, when the average is .83 inches. In May, average rainfall drops to .31 inches, and .06 inches in June.

Los Angeles averages 15.14 inches of rain a year.
