The disturbance has steadily weakened the past 24 hours, and so has the shear over Beta. By the time Beta makes its expected landfall near the Nicaragua-Honduras border Sunday morning, the shear will drop to five knots, which could allow rapid strengthening. There is not much time, though, for Beta to make it to Category 3 status, and the most likely strength at landfall is as a Category 2 hurricane. However, the latest microwave satellite data from NASA's TRMM satellite shows a pinhole eye--a very small 10-mile diameter eye like Wilma developed just before her rapid deepening phase. This may portend a rapid intensification cycle to Category 3 strength or higher may occur today. The hurricane hunters will be in the storm beginning at about 3 pm EDT today to check on its strength
Now the update from Yahoo:
PUERTO CABEZAS, Nicaragua - Thousands of Nicaraguans in boarded-up homes or shelters braced for the arrival of Hurricane Beta early Sunday after the storm steadily gathered strength overnight. The outer bands were already thrashing the mainland with heavy rains and high winds.
Nicaraguan President Enrique Bolanos declared a maximum "red alert" late Saturday, ordering everyone to stay inside. He said some 45,000 people from the port regions were either secured in their homes or holed up in 15 shelters provided by the government.
At 4 a.m. EST, the National Hurricane Center in Miami said Beta's winds had picked up to 115 mph and it was upgraded to a major Category 3 storm. It was expected to make landfall within hours on Nicaragua's east coast.
