In the Baton Rouge area, scattered showers and thunderstorms can be expected through early Sunday morning. Brief downpours will be possible. It will be breezy, but high winds are not anticipated. Impact to the Baton Rouge area from Hurricane Nate is expected to be minimal with the exception of Gulf and lake shorelines where there is a threat for storm surge. See below for a full description of potential impacts. Conditions will improve quickly on Sunday. Showers will end and some breaks of sunshine will be possible.
Alerts: A *TROPICAL STORM WARNING* has been issued for parts of the WBRZ Weather forecast area including northern Tangipahoa, Livingston, Ascension, Assumption and St. James Parishes. Where more significant storm surge is expected, a *HURRICANE WARNING* has been issued for southern Tangipahoa Parish south and east through New Orleans to coast.
Impact: Given the current forecast, tropical storm conditions will be possible in southeast Louisiana, with hurricane conditions possible near the immediate coast. At this time, impact to the Baton Rouge Metro area are expected to be minimal.
SURGE: High water will continue on shorelines and The National Weather Service has issued a *STORM SURGE WARNING* until Sunday evening due to this threat. Water levels could reach 1 to 3 feet above ground on the shore of Lake Maurepas, 3 to 5 feet above ground on the shore of Lake Pontchartrain, 4 to 6 feet above ground from Morgan City to the mouth of the Mississippi River and 7 to 11 feet above ground from the mouth of the Mississippi River eastward to the Mississippi/Alabama border.
WIND: The chance for tropical storm force winds is minimal in the WBRZ Weather forecast area, with a 30 percent chance of winds over 39mph in Hammond down to less than 10 percent chance for Baton Rouge and points to the west. New Orleans and areas east have a greater than 70 percent chance of winds over 39mph.
RAIN: Nate will be a fast mover. Therefore, 1 to 3 inches, and possibly less, appears to be possible over the weekend with the lowest amounts near the Atchafalaya Basin and isolated higher amounts eastward toward Mississippi. Additionally, the threat for tornadoes should be lower in the Baton Rouge area than states east.
Actions: As a rule, it is always good to prepare for one category higher than what is forecast. In this case, since a category one storm is expected, prepare for a category two storm in the event of last minute strengthening. Those with coastal interests should finalize necessary precautions by Saturday morning. On shorelines, expect inundation and move belongings to higher areas as possible. Listen to evacuation orders if issued, and leave by Saturday morning as roads may become impassable thereafter. Inland, secure loose objects outside, as they could become fly around in strong wind. Prepare for possible power outages. Be sure to have a week’s worth of drinking water, non-perishable food, pet food, propane for grilling and extra battery power for flashlights and mobile devices.
