Terrebonne Parish Office of Homeland and Security provides the following update concerning Tropical Storm Cristobal:
Changes From Previous Update:
- The tropical storm watch has been upgraded to a tropical storm warning across coastal areas of SE LA and MS.
- The storm surge watch has been upgraded to a storm surge warning for immediate coastal areas from the mouth of the MS to Ocean Springs.
- The storm surge watch has been expanded westward from Grand Isle to Morgan City.
- TS Winds are now expected to reach the coast slightly early than previously forecast (early Sunday morning).
TS Cristobal is forecast to move northward through the Gulf of Mexico and gradually strengthen over the weekend
On this forecast track, we expect impacts to begin across portions of SE LA and coastal MS by early Sunday morning
Confidence:We have moderate confidence in the impacts associated with this storm.
Several rounds of potentially heavy rainfall are possible, with some rounds well ahead of the storm. Flash flooding will be possible - especially where any rain bands result in prolonged periods of heavy rainfall
Coastal flooding is expected due to storm surge. The following inundation depths are forecast: 3-5 ft from the mouth of the MS River to Ocean Springs 2-4 ft from Morgan City to the mouth of the MS River 1-3 ft from Ocean Springs to the MS/AL border 1-2 ft around the shores of Lakes Pontchartrain and Maurepas
Sustained tropical storm force winds are possible across all of SE LA and SW and Coastal MS. Strong tropical storm force winds (greater than 58mph will be possible across immediate coastal areas of SE LA)
The greatest impacts (highest winds, surge, and rain) could occur well away from the center of the storm depending on its structure as it approaches the coast.
