Tropical Storm Delta formed Monday morning and is expected to make landfall in Louisiana, forecasters said. UPDATE: Tropical Storm Delta strengthening: See latest trackThe current track from the National Hurricane Center has Delta making landfall Friday as a Category 2 hurricane in southeast Louisiana, but the track has an average error of 160 to 200 miles this far out. Heavy rain, dangerous storm surge and gusty winds are all possible, depending on the track and intensity of the system, along the coast from Louisiana to the western Florida panhandle, forecasters said. Now is the time for residents to make plans and prepare. Forecasters also are watching Tropical Storm Gamma, which is weakening in the Gulf of Mexico. It is near the Yucatan peninsula and is not expected to reach the U. S. Gulf Coast. Here's what to know about the tropics as of Monday morning. Tropical Storm Delta forms in the Caribbeanimage via National Hurricane CenterAs of 7 a.m., Tropical Storm Delta was about 130 miles south of Negril, Jamaica, and about 270 miles southeast of Grand Cayman. The storm is heading northwest at 9 mph. It's expected to pick up speed Tuesday and Wednesday. On the forecast track, the center of the storm is expected to move away from Jamaica later in the day, move near or over the Cayman Islands Monday night and approach the Isle of Youth and western Cuba Tuesday afternoon or evening. Forecasters said the long-term track becomes complex because they are unsure how Tropical Storm Delta will interact with the remnant of Tropical Storm Gamma. The interaction ''could result in a sharp westward jog, after which a sharp turn back toward the northwest could occur,'' according to Stacy R. Stewart, a senior hurricane specialist with the National Hurricane Center. Tropical Storm Delta formed Monday morning in the Caribbean, forecasters said. Its current track has it making landfall on the Gulf Coast.

The long-term track, which often changes, has the storm making landfall Friday near Terrebonne and Lafourche parishes and then turning east toward New Orleans and then heading into Mississippi. Delta's winds could reach Louisiana as early as Thursday morning, forecasters said, but the most likely timing is Thursday night. Will it strengthen?image via National Hurricane CenterTropical Storm Delta has sustained winds of 40 mph. Additional strengthening is expected during the next few days, and the tropical storm is expected to be a hurricane when it moves near or over western Cuba.
