Hurricane Issac’s remnants have the potential to produce up to six inches of precipitation around here late Friday through Sunday.
At 5 PM Eastern the center of Hurricane Isaac was about 30 miles south-southwest of the mouth of the Mississippi. Isaac is moving toward the northwest at about 8 mph and should reach the coastline of southeastern Louisiana Tue. evening around 10 PM. Maximum sustained winds have increased to near 80 mph.
Storm surge could still range from 6-12 feet. Rainfall totals of 7-14 inches will be widespread. I’ve attached a national precipitation outlook that models the forecast for the next five days. It indicates the possibility of 3-6 inches of rain over Central Indiana from the remnants of Isaac over Labor Day Weekend.
Going into today the Indianapolis rainfall deficit is 6.44 inches for the year. Things were much drier before this month. In fact, with the 1.42 inches of rain Monday… this is now the 8th wettest August of record in Indianapolis!
The Indy weather station has received almost as much rain in August as it did during the months of April+May+June+July combined. So far this month: 6.46 inches. With more to come this weekend.
GLASS HALF-FULL:
Tomorrow is the the 7th anniversary of Katrina’s landfall, and so Isaac has prompted comparisons. It won’t be close. Katrina at one point reached Category 5 status with winds of more than 157 mph and it made landfall as a Category 3 storm.
