President Obama plans another political visit to Seattle next week as part of a West Coast fundraising spree.

Obama will travel to the state Tuesday to attend an event for the Democratic National Committee, according to the White House.

The presidential motorcade will arrive at a time when traffic in the region likely will be snarled by lane closures on Interstate 90.

The afternoon reception will take place at a private residence in Seattle with about 250 supporters, according to Democratic Party officials. The exact location and other details were not immediately disclosed.

Obama won’t stay long, flying to San Francisco to spend the night before attending a Wednesday fundraiser for the Democratic Congressional Campaign Committee. On Thursday, Obama will be in Los Angeles for additional events.

It’s not clear how Obama’s visit will affect Seattle-area traffic, which will already be hampered by the weeklong closure of parts of I-90 for bridge repairs. Officials were predicting 10-mile backups on westbound I-90 as a result of lane closures.

Presidential visits usually include temporary freeway shutdowns to make way for the commander-in-chief’s motorcade.

Bart Treece, a spokesman for the state Department of Transportation, said there are no current plans to alter the bridge construction schedule as a result of the visit.

He said drivers should be aware the motorcade could further complicate Tuesday’s commute — and plan accordingly.

A White House official said additional details about Obama’s visit will be revealed in the coming days.

The trip comes as Obama and Democrats prepare for the 2014 midterm elections that could hand Republicans a majority in the U.S. Senate.

Obama last visited Washington state in April, flying over the site of the Oso mudslide and meeting with emergency responders and families of the slide victims.
