With eyes watching TD 19 today as it moves slowly WNW into the Gulf and towards the northern shore, you should be aware that slow-moving hurricanes can often cause more damage than fast-moving storms. That is because the strong winds and heavy rains can last over an area for any hours, pounding the buildings with damaging wind gusts and dropping feet of rain. In recent years, we have seen these slow-movers more often than in the past, which means increased damage. Hurricanes Florence and Harvey come to mind, but there have been slow-moving storms in the past that have also brought problems. For example, Tropical Storm Alberto stalled out over southwestern Georgia in July 1994, bringing almost two feet of rain to some places and causing tremendous flooding as far north as Macon. Georgia set their record 1-day rainfall of over 21 inches during that storm. Popular Science has a new article which describes why slow-moving hurricanes are so dangerous at https://www.popsci.com/story/environment/hurricane-stall-danger/.

Rainfall totals through 8 a.m. Tuesday from Harvey. (Jordan Tessler)
