UPDATE | New storms hit flood-weary Houston

New thunderstorms are snarling traffic in the flood-weary Houston area but don't appear to be exacerbating the problems in parts of the flood-battered city.

Harris County Judge Ed Emmett says the good news today is that the heavy rainfall is in a different area of the region than those most affected Tuesday. But county officials say additional rainfall could lead to problems on bayous, creeks and rivers.

Some scattered spots on service roads along Interstate 45 north of Houston were flooded but main lanes were moving.

About 2½ inches of rain were recorded in north and northwest Harris County Wednesday with a line of storms that began just before dawn. More than double that amount has been reported in more rural counties northwest of Houston.
