A year ago this week, a sluggish low pressure system unloaded rain in the area that mirrored a June event that occurred in 2002 when Tropical Storm Allison stalled over Texas. As noted in a previous column, on June 8, the remnants of the storm drifted south, re-forming in the Gulf and moved inland over Louisiana on the 11th. On June 14th it tracked northeast, stalling over North Carolina. For three days it wandered around the mid-Atlantic, merged with a cold front and dissipated in Nova Scotia. Allison was a tremendous rain machine dumping 36.99 inches on Houston and more than 20 inches in Baton Rouge. It caused $5 billion damage and 41 deaths and became the costliest and deadliest U.S. tropical storm on record.
