A broad area of low pressure that AccuWeather has been monitoring over the last couple of days has become better organized and is now a tropical depression about 350 miles southwest of Mexico. This system will move over warm waters and through an area of low wind shear, which should allow it to strengthen into a tropical storm later today or tonight. This system will be named Rosa once it reaches tropical storm strength. Further strengthening is likely by the end of the week and this system is expected to become a hurricane Thursday. As this system moves even more to the north this weekend, it will move over progressively cooler waters. It is too early to know exactly where the system will track, but there is the potential it can eventually move into northern Mexico and the southwestern United States early next week.
We are watching another area of low pressure about 1,600 miles southwest of Hawaii. There is some potential that this system will become more organized later this week.
