The US drought monitor declared 60% of the country to be in a designated drought zone last Thursday, with 34% in a severe or deepening drought. Although such conditions are not unusual in the US, with approximately 14% of the country having experienced severe to extreme drought every year since 1895, the extent of the current situation certainly is.
Western states and parts of the Great Plains are experiencing the most severe droughts in the country. Some central states including Minnesota and Iowa have recorded less than 25mm of rain in the past month, compared with an average of 70-100mm in September.
