The Global Precipitation Measurement mission or GPM constellation of satellites provide data on precipitation rates and totals. Recently the GPM core observatory measured the heavy rainfall that caused extensive flooding and loss of life in Peru.
Extreme flooding and frequent landslides that occurred in March have forced many from their homes. An El Niño-like condition with warm ocean waters developed near Peru's coast. This extremely warm water off Peru's western coast has been blamed for promoting the development of these storms. Equatorial sea surface temperatures (SSTs) are about average elsewhere in the central and east central Pacific.
