A. Situation Analysis

In the north-eastern region of Brazil, the rainy season starts in May and extends through July.
Atmospheric conditions continued to be unstable from 21 to 31 May 2017, which was increased on 27 and 28 May. A combination of low- and high-level winds, originating in the Atlantic Ocean, brought significant rainfall.

Rainfall monitoring stations in Alagoas and Pernambuco states registered record levels of accumulated rainfall in a 24-hour period. On 27 May, the automatic station in Maceió (Alagoas) recorded 152.4 mm of rain, surpassing the previous record of 147.8 mm rain set on 5 June 2010. On 29 May, the automatic station in Joao Pessoa (Pernambuco) registered 129.8mm, considered the fourth highest level registered in Pernambuco state. Within the context of heavy rains and floods, the epidemic area of the Ministry of Health has alerted the population regarding the risk of proliferation of the Aedes aegypti mosquito that transmits dengue, Zika and chikungunya.
