NEW ORLEANS —
Tropical Storm Beta
10 p.m. Sunday update:
The new forecast path for Beta shows it weakening to a depression by late Tuesday. Beta is moving slowly west-northwest at 6 mph. Winds remain the same at 60 mph, but the storm's center jumped west earlier on Sunday as a burst of thunderstorms pulled the low level center west.
The National Hurricane Center's path takes the storm into Texas or close to the Texas coast late Monday.
The 10 p.m. Sunday forecast path for Beta shows it weakening on Monday, which is expected because of a lot of dry air wrapping around it, plus significant shear. It is forecast to weaken to a depression by late Tuesday.
Beta has been struggling due to dry air wrapping around from the western side, but it's possible the storm pulse up in down in intensity as it battles the dry air. The upper shear is still present.
As for steering of the storm... a building ridge is directing the storm westward, and that should continue into Monday. Beta may then slow down or become stationary over extreme southeast.
A trough of low pressure will deepen late Tuesday to Wednesday and push the likely much-weakened system toward western and northern Louisiana.
Impacts for southeast Louisiana will be rainfall, possibly 3-5 inches with isolated 7 inches or higher. There could be some changes to the numbers, but we'll need to be prepared in case of a heavy rain band particularly Monday night or Tuesday.
We also expect coastal flooding of 2-3 feet along the coast and in Lake Pontchartrain. Rainfall forecasts are not set in stone - there could be changes.
Winds will remain breezy through much of this week as Beta remains in the region.
Most of the effects from Beta will end by late Wednesday. A few showers could continue into Thursday and Friday.
The National Hurricane Center is now giving a near 0 percent chance of development for a tiny low pressure area over Florida. Strong upper winds should prevent it from developing, and we're not expecting much from it aside from a potential for some enhanced moisture over our area at the middle or end of the week.
Farther out in the Atlantic, Hurricane Teddy is heading toward Bermuda. The storm should start to weaken as it approaches the island thanks to cooler waters, but could still bring impacts by Monday. It could then continue on toward Nova Scotia or Newfoundland.
Another tropical wave coming off the coast of Africa has a medium chance of development over the next few days.
