James Spann: Quiet afternoon for Alabama; hurricane forecast in the Gulf this weekend

RADAR CHECK: So far showers and storms are very hard to find across Alabama this afternoon; the sky is mostly sunny with lower heat levels today. Temperatures are mostly in the mid to upper 80s. We will have a chance of isolated showers through the evening, but it looks like most places will be dry through tonight.

FRIDAY THROUGH SUNDAY: We expect routine weather Friday through the weekend — partly sunny days with scattered showers and storms, mostly from noon to midnight. The chance of any one spot getting wet each day is 20-30%, and highs will be between 86 and 90 degrees.

NEXT WEEK: Ida is expected to make landfall on the Louisiana coast Sunday evening, and Alabama will be on the wet, unsettled side of the circulation. This will bring potential for widespread rain Monday and Tuesday, along with potential for flooding and a few tornadoes. But there is still considerable uncertainty in the track, and it is a little early to define where the greatest flood and tornado threat will be. The weather trends drier over the latter half of the week.

TROPICS: Two tropical waves in the Atlantic now have a high chance of becoming a tropical depression or storm over the next five days, but those are not expected to affect the U.S.

TROPICAL DEPRESSION NINE: Newly formed Tropical Depression Nine is forecast to become Tropical Storm Ida soon. The system is west of Jamaica, in the Caribbean, and is moving northwest at about 15 mph. The National Hurricane Center is forecasting the system to reach hurricane strength in the southern Gulf of Mexico Saturday morning, followed by landfall on the Louisiana coast Sunday afternoon or evening.

The NHC intensity forecast brings the system near major hurricane strength when it approaches the Louisiana coast on Sunday. This forecast is supported by model guidance, which all significantly deepen the cyclone over the Gulf of Mexico. As a result, there is higher-than-normal confidence that a strengthening tropical cyclone will be moving over the Gulf this weekend. There is a risk of life-threatening storm surge, damaging hurricane-force winds and heavy rainfall Sunday and Monday along the northern Gulf Coast from the Florida Panhandle to the upper Texas coast, with the greatest risk along the coast of Louisiana.

COASTAL IMPACT: It is too early for a specific impact forecast for any point on the Gulf Coast since the system has just formed and is still in the Caribbean. Remember the main impact in terms of wind, flooding and storm surge will be east of the landfall point. For now, it looks like the highest impact will come across southeast Louisiana and the Mississippi coast, but there will be some rain and wind as far east as the Alabama and northwest Florida coasts. Dangerous rip currents are likely all along the central Gulf Coast Saturday through Monday; expect double red flags.

We will be much more specific on the coastal impact for places like Gulf Shores, Destin and Panama City Beach on Friday.

INLAND IMPACT: Ida will likely bring the threat of flooding to much of Mississippi and Alabama Sunday night through Tuesday. Rain amounts could easily exceed 6 inches across parts of these two states, but again it is too early to define the axis of the heaviest expected rain. Isolated tornadoes will be a possibility Monday and Tuesday across east Mississippi and Alabama.

Please keep up with the latest updates on this tropical system as it moves toward the Gulf Coast over the next few days. If you are working with old information, you are working with bad information.

ON THIS DATE IN 1976: A weak tornado touched down briefly in the Hockley Hills near Kiana, Alaska, about 29 miles north of the Arctic Circle. This tornado is the most northerly report of a tornado on record. Kiana is 545 miles northwest of Anchorage.

ON THIS DATE IN 1992: Hurricane Andrew made a second landfall near Burns Point, Louisiana, as a Category 3 hurricane. Morgan City, Louisiana, recorded sustained winds of 92 mph with a peak gust of 108 mph. Hammond, Louisiana, was deluged with 11.92 inches of rain. As Andrew moved inland and weakened, it spawned 47 tornadoes from this date through Aug. 28 from the South to the Mid-Atlantic states.
