Here is an update concerning Hurricane Marco and Tropical Storm Laura.
Changes from previous update:
Hurricane Marco is forecast approach the coast on Monday, bringing coastal flooding, heavy rainfall and gusty winds to SE LA and S MS
Tropical Storm Laura is forecast to be at least a category two as it approaches the Northwest Gulf coast on Wednesday
We are confident Marco will bring impacts to the local area
We are confident Laura will bring some impacts (mainly potential for coastal flooding and heavy rain) to the local area, but less confident in the magnitude of impacts
Impacts from Marco:
Rainfall of 3 to 6 inches with locally higher amounts of double or more will be possible
Expect ponding of water in low lying areas and some potential for localized flash flooding
A Flash Flood Watch is in effect for the lower parishes of southeast Louisiana. This watch may be expanded, depending on future track adjustments.
Sustained hurricane force winds are unlikely across land areas, but could occur in gusts along the coast of SE LA
Sustained tropical storm force winds will be more widespread across extreme SE LA, with tropical storm force gusts possible farther inland
These winds could result in minor damage mainly to trees, powerlines, and weaker structures.
TS Laura could bring additional coastal flooding and heavy rainfall, as well as gusty winds to portions of the area mainly west of the MS River
Keep in mind that preparation for TS Laura may be made more difficult by lingering impacts from TS Marco.
