A glacier collapse near Nepal's border with China set off catastrophic flooding that has killed more than 600 people, with thousands still missing — a disaster now being felt by Nepalese families in Hawaii.

• More than 600 people are confirmed dead after floodwaters tore through the region.
• About 2,500 people are still missing, including Americans and other foreigners.
• Experts believe a collapsing glacier released the wall of water.
• Hawaii's Nepalese community is tracking the search closely, with many worried about relatives back home.
• The immediate need on the ground is food, shelter and basic supplies for survivors.

Outlook: Rescue crews will keep searching for the missing, and the death toll is likely to rise as more areas are reached.
