What We're Following This Evening

An impeachment vote in Brazil: Legislators are considering impeachment proceedings against President Dilma Rousseff, who is alleged to have hidden the true state of the government’s troubled budget during her 2014 reelection. If both chambers of Brazil’s Congress vote this week that impeachment is in order, Rousseff would have to step down from her post for up to 180 days while a trial is held.

Zika outbreak: A CDC official says the mosquito-borne virus that has spread across Latin American countries in recent months is “a bit scarier than we initially thought.” The agency says the mosquito that spreads Zika is now present in about 30 states and Puerto Rico. Julie has the latest on Zika’s link to neurological conditions here, and Adrienne writes about the virus’s potential effects on low-income U.S. communities here.

The end of an era: The National Weather Service announced that it will cease using SHOUTY CAPS in its forecasts starting in May, ending a practice that began in 1849, when meteorologists used the telegraph to warn people of impending storms, and not frantic tweets. Rob wrote about the uppercase forecasts in January, and rest assured he’s drafting a eulogy for them right now.
