Combing climate data with travel patterns, researchers with the Center for Disease Control and the National Center for Atmospheric Research say Zika virus outbreaks could occur as soon as this summer in parts of south Texas and Florida.
The study shows that the Aedes aegypti mosquito, which is spreading the virus in much of Latin America and the Caribbean, probably will become more abundant across much of the southern and eastern United States as the weather warms.
El Niño didn’t exactly go gangbusters in southwest Colorado last month, where the key river basins received only about 35 percent of average February precipitation. Statewide mountain precipitation was only slightly better, at 56 percent of normal.
“February in the mountains of Colorado is typically a slightly drier month than compared to say, April. But a dry February like this could have big ramifications should April and May not pan out” said Brian Domonkos, Snow Survey Supervisor with the Natural Resources Conservation Service.

Winter brings extraordinary ‘heatwave’ to the far north
Arctic sea ice was at a record low extent for the second month in a row in February, according to the National Snow and Ice Data Center. Ice researchers said sea ice grew hardly at all during the first three weeks of the month during a time of year when the sea is extent is usually nearing its peak.
Although there are still a few months left in the rainy season, this year’s El Niño hasn’t exactly been the drought buster California was hoping for. Thus far, plentiful precipitation in the northern part of state will go a long way toward replenishing reservoirs, but central and southern California have remained relatively dry.
The “exceptional drought” footprint is now spread across about 38 percent of the state, as compared to 45 percent three months ago, and precipitation in the key snowpack areas of the Sierra Nevada has been about average. Farther south, especially in the L.A. Basin, precipitation is still well below average for the rainy season to date.
