Weather forecasts have improved greatly in recent decades. Three-day hurricane forecasts that were off by an average of 300 miles in 1990 were only off by 100 miles in 2010, a dramatic improvement in just 20 years. And, much of the improvement can be attributed to critical data gathered by weather satellites.
However, a recent report by the Government Accountability Office listed a potential upcoming gap in weather satellite coverage as one of the "Top 30 Challenges facing the federal government." Mismanagement, overspending, and poor planning have led to the possibility of a gap in satellite data as soon as next year ... and the report says the gap could last more than four years if nothing is done to address the problem.
