One town was an island and an unknown number of people homeless Friday in the flood-stricken state, and Tennessee suffered a fifth consecutive day of rain. Kentucky Gov. Wallace Wilkinson was expected to seek a federal disaster declaration; Tennessee Gov. Ned McWherter asked for similar relief Thursday. Parts of the two states received more than 10 inches of rain in a week, flooding roads, closing schools and claiming at least three lives.
