Fires Plague Portugal (IMAGE) NASA/Goddard Space Flight Center Caption Portugal has been experiencing the worst drought in years. Drought and the dry conditions that follow lead to wildfires set by just a spark or a lightning strike. Portugal's north has been plagued with wildfires due to these such conditions. Spain and France have joined their firefight lending water-dumping aircraft in an effort to quell the raging fires. The dry conditions, heat, high winds, and difficult terrain in the area where the fires have been most active have produced what the firefighters over there have dubbed "the perfect storm."
