A Flash Flood Watch is in effect until noon – an additional 1-2″ with locally higher amounts possible, but all need to prepare for potential flooding issues. Backwater flooding is going to be an issue. You can view river observations and river forecasts here or here.
A Coastal Flood Warning and Costal Flood Advisory are in place. Inundation will be around 1-2′ for advisory areas and 2-3′ for warning areas during high tide cycles through early Saturday – Strong easterly and southeasterly wind will cause this for areas near Lake Maurepas and Ponchartrain, as well as near coastal zones.
Today: There is a disturbance in the western and northwestern Gulf of Mexico. The NHC is giving Invest 91L a medium chance of development before it moves toward the Texas coast tonight. It may briefly become a tropical depression or tropical storm before moving inland tonight. This will enhance the heavy rain threat to our west. Our rain chance will be highest this morning and early afternoon. We’ll see scattered to numerous showers and isolated storms, but not all areas will see rain thanks to high pressure building to our east. Rain chance is around 60%. High near 80°F.
Tonight: We will finally begin to dry out. Partly to mostly cloudy and breezy with lows near 66°F.
Saturday: A few early showers are possible for western areas. Otherwise, it’s going to breezy and we’ll see sun and clouds with highs near 85°F. Overnight temperature near 63°F.
Sunday: Sun and clouds with highs near 86°F, but it will feel a bit hotter. Overnight temperature near 65°F.
Next Week: We stay dry to start the week with highs near 88°F. A few showers may be around by Wednesday and Thursday.
Tracking the Tropics: Meanwhile, in the open Atlantic, Invest 90L will likely become a subtropical system later today. It will not impact the United States. First name on the list is Ana, then Bill.
