SHREVEPORT, La. (AP) _ Storms dumped five inches of rain over northwestern Louisiana today, causing at least one fatal accident and filling some homes with up to 4 feet of water, officials said.

Chester Dale Heald, 56, of Keatchie, was hit by a truck and killed while directing traffic around a car which had hit a fallen tree, said Caddo Parish Sheriff Don Hathaway.

The truck driver was seriously hurt, he said, while the pregnant woman who had been in the car was taken to a nearby fire station where firefighters delivered her son. The mother was then taken to a hospital for treatment of chest injuries.

National Weather Service meteorologist Mark Murphy said two more inches of rain were expected before the storms moved out.

''This is on top of almost continuous rain for the past eight days,'' said Civil Defense Director Chuck Mazziotti.

Mazziotti said four neighborhoods had flooded.

''Probably most of them have just a few inches. But there is three to four feet of water in a few homes,'' he said. ''We don't have a count on how many homes are affected. Many intersections and roads are flooded out.''

He said boats and four-wheel-drive vehicles were being gathered in case they were needed, but all the people who had needed to leave their homes this morning had been able to get out on their own.
