WASHINGTON  The White House predicted Monday that President Bush would leave a record $482 billion deficit to his successor, a sobering turnabout in the nation’s fiscal condition from 2001, when Mr. Bush took office after three consecutive years of budget surpluses.

The worst may be yet to come. The deficit announced by Jim Nussle, the White House budget director, does not reflect the full cost of military operations in Iraq and Afghanistan, the potential $50 billion cost of another economic stimulus package, or the possibility of steeper losses in tax revenues if individual income or corporate profits decline.

The new deficit numbers also do not account for any drains on the national treasury that might result from further declines in the housing market.

The White House forecast was prepared before passage of the huge housing assistance package that Mr. Bush has promised to sign. That legislation would put taxpayer money at risk in numerous ways, especially if housing prices continue to decline.
