Following the reestablishment of the democratic government after the ouster of Ferdinand Marcos (see People Power Revolution) in 1986, President Corazon C. Aquino ordered the reorganization of the National Science and Technology Authority (now called Department of Science and Technology) and all agencies under its authority, pursuant to Executive Order 128, s. 1987 Five major branches (Weather, Flood Forecasting, Climatology & Agrometeorology, Astronomical, Geophysical & Space Science, and National Disaster Reduction) and three support divisions (Administrative, Finance & Management, and Engineering & Maintenance) now constitute PAGASA. This organizational structure remained until October 2008, when the agency went under a Rationalization Program pursuant to Executive Order 366, s. 2004 issued by President Gloria Macapagal-Arroyo. The Rationalization Program of the government was aimed at making the government focus its efforts on vital/core functions and enhance effectiveness and efficiency of public service.
