(Adds full-year forecast, share movement)

Aug 16 (Reuters) - Nordstrom Inc reported better-than-expected quarterly same-store sales growth on Thursday, as more people shopped at its online stores, leading the department store operator to raise its full-year profit forecast.

Shares of the Seattle, Washington-based company rose 11 percent to $58.30 in after-hours trading.

For 2018, Nordstrom now expects an adjusted profit of $3.50 to $3.65 per share, compared with its previous forecast of $3.35 to $3.55.

Nordstrom managed to report upbeat results despite the broader retail environment plagued by bankruptcies, store closures, fast-changing fashion trends and discount-hungry shoppers who favor buying online.

Same-stores sales rose 4 percent in the second quarter ended Aug. 4, beating the average analyst estimate of a rise of 0.81 percent, according to Thomson Reuters I/B/E/S.

Online sales rose 23 percent and accounted for 34 percent of total sales.

Excluding items, the company earned 95 cents per share, beating estimates of 84 cents, according to Thomson Reuters I/B/E/S.

Net sales rose about 7 percent to $3.98 billion, higher than the $3.72 billion analysts had expected. (Reporting by Karina Dsouza in Bengaluru; Editing by Maju Samuel and Sweta Singh)
