Hurricane Zeta made landfall on Mexico's Yucatan Peninsula late Monday night and into early Tuesday morning as a category one hurricane packing winds of 80 mph.

The storm has weakened a bit this morning due to land interaction with the Peninsula. Winds are at 65 mph.

It is forecast to maintain category one strength up until landfall in SE Louisiana sometime on Wednesday evening.

The steering currents for this storm remain pretty straightforward and clear.

Zeta will initially move northwestward today around the outer periphery of high pressure that is anchored near Florida.

That high pressure will start to slide eastward into the Atlantic giving way for Zeta to start moving northward.

Meanwhile, a strong upper-level trough and associated cold front will be moving in from the west.

That will start to steer the storm more northeasterly on its approach to the coast.

So, a hard bend to the right is anticipated as it nears landfall.

The same upper-level trough will also provide some amounts of wind shear meaning a lot of the deep convection and worst of the impacts will remain near and east of the center of circulation.

Thus, since we will remain on the western side of this storm, we will be spared from the worst of the weather impacts.

However, rain chances will still be elevated on Wednesday no matter what due to a cold front associated with the trough moving in bringing rounds of showers and storms.

We can also expect a breezy day on Wednesday as winds gust to around 20-30 mph (upwards to 40 mph along the coast and eastern Acadiana).

Tides are still expected to come up a bit to around 2-4 feet along the coast even though northerly winds will create more of an offshore flow as the storm passes to our east. This includes Vermilion Bay.

Tropical Storm watches remain in effect for our coastal parishes for the potential to see tropical storm force wind gusts at times.

The good news is that Zeta will be a fast mover.

Expect clearing skies, plenty of sunshine, and much cooler temperatures behind the front on Thursday afternoon.

The cooler weather will continue for Friday and the upcoming weekend.

We will be talking high temperatures in the mid and upper 60s with overnight lows in the upper 40s to lower 50s.
