Weather Boston

Hurricane Irene is coming. Hopefully not. All of the reliable forecasters, including the National Weather Service's Hurricane Center, predict today Boston and Massachusetts are smack in the center of the probable track of Hurricane Irene.
But, four days ago, A severe thunderstorm watch is in effect from Massachusetts to Delaware, the National Weather Service said. Downed trees and large hail have been reported.

Doppler Radar

Like in the movie Tornado, we can use A Doppler radar to produce velocity data about objects at a distance, also, we can use it to detect the velocity of a vehicle running (the police use it) and we can use it as a weather radar.
A Doppler Radar could gave a 12-minute tornado warning as a weather radar.

A doppler radar does this by beaming a microwave signal towards a desired target and listening for its reflection, then analyzing how the frequency of the returned signal has been altered by the object's motion.

Monday’s unusual storm which brought more than 2 inches of rain to the West End on Monday was “seen” for the first time by the region’s new weather radar system.

Installed only since spring, the new Doppler radar station near Ocean Shores in Grays Harbor County helped the National Weather Service issue a flood advisory Monday for the West End.

The domed tower is still in the testing mode, but its radar detected heavy bands of rainfall from Cape Flattery to Ocean Shores, said Jay Albrecht, National Weather Service meteorologist in Seattle.
“It’s beautiful, actually,” he said.
“It showed all the rain. We were able to see heavy precipitation in Forks.”

Until now, the Weather Service’s Doppler station on Camano Island near Everett was blinded by the Olympic Mountains, leaving an undetected “hole” on the Pacific coast.
“Forks received more than 2.6 inches of rain in just five hours,” said Jay Albrecht, National Weather Service meteorologist.
