But usually, loss of vision in one eye isn't related to migraine. These bouts may precede or accompany a headache.Ī retinal migraine - unlike a migraine aura - affects only one eye, not both. Retinal migraine involves repeated bouts of short-lasting diminished vision or blindness. Ocular migraine sometimes is used as a synonym for the medical term "retinal migraine." A retinal migraine is a rare condition occurring in a person who has experienced other symptoms of migraine. But migraine with aura isn't usually considered serious. These symptoms can temporarily get in the way of certain activities, such as reading or driving. A migraine aura involving your vision will affect both eyes, and you may see: Aura can sometimes occur without a headache.Ī migraine aura that affects your vision is common. The auras usually last for about five minutes to an hour. If the wave of activity goes through other areas of the brain such as the sensory or language centers, then the person would have sensory (for example, tingling in the tongue, face or arm) or language auras. It's thought that auras are usually visual because such a large portion of the brain processes visual information. About 90% of people who have migraine with aura have this type. The most common type of aura is a visual aura. The location of the wave of activity in the brain determines the type of aura. Migraine aura is a wave of activity in the brain traveling through the brain. When visual changes are only in one eye, they could signal something serious and require immediate treatment. Retinal migraine is extremely rare, and the visual changes are in only one eye. This scenario would keep Lee farther away from the US coast but could bring the storm closer to Bermuda.Most commonly the term "ocular migraine" had been used to describe what is now called migraine with aura. If the jet stream sets up along the East Coast, it will act as a barrier that prevents Lee from approaching the coast. Lee could make a quick turn to the north early next week if high pressure weakens significantly. Once that turn to the north occurs, the position of the jet stream – strong upper-level winds that can change the direction of a hurricane’s path – will influence how closely Lee is steered to the US. The Bermuda High is expected to remain very strong into the weekend, which will keep Lee on its current west-northwestward track and slow it down a bit.Īs the high pressure weakens next week it will allow Lee to start moving northward. Lee's potential track next week will be determined by multiple atmospheric factors including a strong area of high pressure to its east (yellow circle) and the jet stream (silver arrows) to its west.Īn area of high pressure over the Atlantic, known as the Bermuda High, will have a major influence in how quickly Lee turns. Several steering factors at the surface and upper levels of the atmosphere will determine how close Lee will get to the East Coast. How close will Hurricane Lee get to the US? Here’s what will steer the storm and two potential scenarios meteorologists are watching for how the US threat could play out. But exactly when that turn occurs and how far west Lee will manage to track by then will play a huge role in how close it gets to the US. The forecast track shows the storm turning to the north over the central Atlantic early next week, but it is not expected to threaten any land areas as of Thursday.Ĭomputer model trends for Lee have shown the hurricane taking a turn to the north early next week. Margot currently has winds of 40 mph and steady strengthening is expected – the center is forecasting Margot to become a hurricane over the weekend. Tropical storm conditions, life-threatening surf and rip currents could occur on some of these islands over the weekend.Īlso Thursday, a tropical depression in the eastern Atlantic strengthened into Tropical Storm Margot, just a few hundred miles west of the Cabo Verde Islands, the center said. ![]() ![]() There is increasing confidence that the center of Lee will pass to the north of the Leeward Islands, the Virgin Islands and Puerto Rico this weekend and into early next week. ![]()
