An announcement made by the National Hurricane Center in Miami revealed that the scientists studying the Tropical Storm Nana reached the conclusion that it is disorganized and that it will weaken over the next few days.

At this point, the storm’s maximum sustained winds reach nearly 40 miles per hour and even though in other cases this would lead to an alarming outcome, the scientists say that the Nana’s upper level winds will not strengthen it.

This morning, the storm was located at about 1,015 miles west of the Cape Verde Islands, moving on its west-northwestern course at a speed of about 7 mph. Its current state is expected to last for a maximum of another two days, slowly weakening as time goes by. ''Winds are not conducive for intensification, and Nana is expected to weaken to a tropical depression later today,'' the center said.

South of Puerto Rico, another system is making its presence known, causing heavy rains in the area. For now it is considered too weak to be named, but its favorable conditions might turn it into a tropical depression, so the scientists are closely monitoring it.

Puerto Rico, the Virgin Islands and the Dominican Republic are all expecting heavy rains this week, and the National Weather Service in San Juan released a flood warning for several areas crossed by the Rio Fajardo river.

The six-month hurricane season, expected to end around November 30 has been rather busy, with six hurricanes formed out of this year’s 14 tropical storms.
