Latest Outlook as Tropical Storm Barry Develops

The National Weather Service expects the primary impact from this system to be heavy rain, with rainfall totals currently predicted in the ten-to-20 inch range in New Orleans and locally higher amounts possible. The greatest risk for heavy rainfall currently appears to be Friday through Sunday. A Flash Flood Watch will continue to remain in effect. 

Elevated tides are possible and coastal flooding may be a problem in some areas beginning Friday. A Storm Surge Watch is in effect for areas outside of the levee system in Orleans Parish, including Venetian Isles, Lake Catherine, and Irish Bayou.

Effects of storm surge have the potential to increase the Mississippi River stage to 19 feet at the Carrollton Gauge on Saturday. The National Weather Service has issued a Flood Warning for the Mississippi River including the New Orleans area through Saturday, July 13. The Southeast Louisiana Flood Protection Authority is closing flood gates along the river, all of which will be closed by Thursday evening.

Strong winds are also expected in squalls Friday and through the weekend. Wind strength will depend on track and development and the most likely arrival of tropical storm-force winds is Friday morning, but could be as early as Thursday evening.
