What precautions are aid agencies taking before the heavy rain?

Heavy rains are expected to fall in a few weeks. Aid agencies are racing to shore up flimsy shelters and stabilize shaky terrain before the monsoon season begins. The U. N. refugee agency says the work ahead is monumental but preparations are off to a better start this year than last. Aid agencies last year had to deal with the massive influx of more than 740,000 Rohingya refugees fleeing violence and persecution in Myanmar.
