A Thai woman walks through the deep flooded streets October 21, 2011 in Pathumthani on the outskirts of Bangkok, Thailand. Hundreds of factories closed in the central Thai province of Ayutthaya and Nonthaburi as the waters come closer to threaten Bangkok as well. Around 320 people have died in flood-related incidents since late July according to the Department of Disaster Prevention and Mitigation. Thailand is experiencing the worst flooding in 50 years.
