MAPUTO, Mozambique (AP) -- The desert nation of Mozambique, still recovering from recent devastating and deadly rains, is bracing for another watery onslaught.

A tropical storm is heading to the country and expected to bring heavy rains and high winds, the South African Weather Bureau in Pretoria said Sunday. It was uncertain when the system would hit land.

The Mozambican floods are reported to have killed 150 people and left hundreds of thousands homeless.

Vast areas of agricultural land have been destroyed in the floods, leading to acute hunger, Radio Mozambique reported Saturday. But President Joaquim Chissano, who inspected flood damages by air Saturday in southern Mozambique, said this year's harvest in the Limpopo Valley did not have to be totally ruined.

``Everything would depend on an efficient supply of seeds to farmers for second sowings,'' he said.

Crews from South African Defense Forces, in Mozambique to aid the rescue effort, have saved about 3,000 people from trees, rooftops and the water in the past week, spokesman Maj. Louis Kirstein said Sunday.

In southern Namibia, about 5,000 people were displaced when the Fish River burst its banks after officials on Saturday were forced to open the sluice gates of the country's largest storage dam because of torrential rains and flash floods.

Botswana has also been drenched by heavy floods.
