Wildfires in Arizona, Nevada, Utah and California
A wet winter season in the southwestern states has produced a thick vegetation growth that is now dry enough to catch fire. Lightning strikes and other events have sparked several wildfires in California, Arizona, Nevada and Utah, some of which can be seen in this satellite image (West Side Complex, Good Springs and Hackberry Complex). Strong winds and hot temperatures have made these fires difficult to contain. They now threaten or have destroyed numerous subdivisions and recreational sites. Many famlies have been evacuated.

Hurricane Evacuation Map
It's hurricane season again and coastal states are getting ready to weather the storms. In the event of a large storm making landfall evacuation plans for thousands of people must be planned in advance to avoid major problems. Louisiana has published a Hurricane Evacuation Map that shows which areas are to evacuate first, the times that they are to evacuate and the roads which will serve as major evacuation routes (all lanes on some of these highways will be used to handle the heavy traffic flow expected. The Louisiana State Police, Louisiana State Deparment of Transportation, the Office of Homeland Security and Preparedness and the American Red Cross coordinated production and printing for one million copies of the map.
Visit the Louisiana Department of transportation website if you want to get a close-up look at the Hurricane Evacuation Map

The US Geological Survey is updating a map of below normal streamflow conditions. Their map gives a general overview of recent drought conditions. Drought conditions are based upon local stream gages recording discharge values that are in the lowest 25th percentile for that date compared to the historical record. This means that of all years that records have been kept at least 75% of the years for that date had higher discharge values.
