Here's the latest from the National Hurricane Center:

  • The center of Tropical Storm Don is currently about 25 miles southeast of Grenada, moving west at 20 to 25 mph.
  • Tropical storm warnings are in effect for portions of the Windward Islands.
  • Don will move across the Windward Islands within the next few hours.
  • Heavy rain and gusty winds will be the main impacts from Tropical Storm Don.
  • Don is then expected to degenerate into a trough of low pressure late Tuesday night or Wednesday in the eastern Caribbean Sea.
  • This system is no threat to the U.S. mainland.


Current Storm Status

Don is a small tropical cyclone, with tropical-storm-force winds extending only up to 35 miles from the center of circulation.

A hurricane hunter reconnaissance mission early Tuesday found a "less-defined" circulation.

The combined nemeses of wind shear – the change in wind speed and/or direction with height – and dry air will continue to take their toll on Don as it moves west into the Caribbean Sea, likely degenerating it into a trough of low pressure within the next 12 to 24 hours.

Don is no threat to the United States.


Projected Path

A tropical storm warning remains in effect for Grenada, St. Vincent and the Grenadines. Tropical storm conditions are expected to spread across the warning area during the next several hours.

The tropical storm watch for Bonaire has been canceled, as Don is expected to degenerate into a trough of low pressure before reaching the island.


Tropical Storm Watches/Warnings

Don may produce total rainfall accumulations of 3 to 6 inches, with isolated higher amounts, across Trinidad and Tobago and the southern Windward Islands through Wednesday.

This may lead to life-threatening flash flooding and mudslides, particularly in mountainous terrain.


Rainfall Forecast

This is a good time to make sure you have a plan in case a hurricane threatens. The Federal Alliance for Safe Homes has an excellent site that can help you make a hurricane plan.

Half of the village of Big Sur, on the coast of central California, has lost its only access to the north following the demolition of the flood-damaged Pfeiffer Canyon Bridge along State Route 1 (also Rt. 1 or SR 1) on March 19. Although Rt. 1 to the south of Big Sur has reopened to traffic (after mud and rock slides were cleared) it is a long 70-mile journey along the windy but spectacular highway to Cambria, the next town of any significance where supplies can be had. CalTrans (California Department of Transportation) estimates it will take 6-9 months to rebuild a new bridge over the canyon.

By now, many of you have heard or read about the arrest of Ahmed Mohamed, a 14-year-old high school student from Irving, Texas. Ahmed was arrested because school officials called the police after he showed one of his teachers his homemade clock. Mistaken for a bomb, Ahmed was taken into custody, interrogated, shamed, suspended (still on suspension today, Wednesday), and reprimanded. All of this after it has been found that the "device" he brought to school was indeed, a homemade clock.
