James Spann forecasts possible high Alabama impact from Zeta tonight from Alabama NewsCenter on Vimeo.
ZETA APPROACHING: Zeta is a hurricane again early this morning in the Gulf of Mexico with winds of 85 mph. It will move into southeast Louisiana late this afternoon and race rapidly through Alabama tonight.
We will deal with periods of rain today with temperatures in the 70s; the main wind and rain associated directly with Zeta will come tonight, and there is potential for a high-impact wind event for much of the state.
GULF COAST: Zeta is expected to bring a storm surge of 6-9 feet for Dauphin Island, 4-6 feet for Mobile Bay and 3-5 feet for Fort Morgan, Gulf Shores and Orange Beach. Winds over Mobile and Baldwin counties could gust to 70 mph in spots this evening; a Tropical Storm Warning is in effect. A few isolated tornadoes or waterspouts are possible this afternoon and early tonight.
INLAND ALABAMA: A Tropical Storm Watch covers much of central and northeast Alabama, where the core of Zeta will be moving through late tonight. That watch will be upgraded to a Tropical Storm Warning a little later this morning. Remember, tropical storm force winds are 39-73 mph.
Because of the rapid movement of the system, Zeta won’t have much time to weaken over inland Alabama. That fast forward motion will also add to the wind potential of the system. Accordingly, this now looks like it has potential to be a high-impact wind event for inland parts of Alabama late tonight; sustained winds of 25-45, with gusts to 65 mph in a few places south of I-59. This will bring the potential for significant tree and power line damage to much of the state late tonight.
- The core of the highest wind for central and northeast Alabama will come from midnight to 6 a.m. The higher winds will be along and south of I-59.
- For any one spot, the highest winds will last about two to three hours.
- The greatest concern will come from falling trees late tonight and before dawn Thursday. If you live in a mobile home surrounded by pine trees, I would consider spending the night in a different place tonight.
- Plan now for power outages.
- A few isolated brief tornadoes are possible overnight as well; the highest risk will come over the southern half of the state.
- Rain amounts over the next 24 hours will be between 1 and 3 inches; a Flash Flood Watch is in effect for much of central and southwest Alabama.
- The wind and the rain will subside early Thursday morning, and the sky becomes partly sunny during the day.
Since this is a considerable forecast change (in terms of the wind situation) from 24-36 hours ago, be sure your friends and neighbors know about the threat late tonight.
FRIDAY AND THE WEEKEND: We are forecasting fine fall weather Friday through the weekend, with mostly sunny, pleasant days and fair, cool nights. The high Friday will be in the mid 60s, followed by highs between 68 and 72 over the weekend. Lows will be mostly in the 40s.
NEXT WEEK: Colder air arrives Monday; we start the day in the mid to upper 30s, followed by a high only in the upper 50s. Some north Alabama communities could see a freeze early Tuesday morning, with lots of frost elsewhere. The high Tuesday will be in the 60s, and the latter half of the week still looks rain-free with pleasant temperatures.
ON THIS DATE IN 1999: A Super Typhoon known as Cyclone 05B reached the equivalent of a Category 5 hurricane. This storm is the strongest tropical cyclone ever recorded in the North Indian Ocean. Cyclone 05B hit the Indian State of Odisha near the city of Bhubaneswar on Oct. 29. An estimated 10,000 people would die from this cyclone and 1.67 million were left homeless.
