As Hurricane Irene moves north, Montgomery County plans to open a shelter for residents at 4 p.m. today at Richard Montgomery High School. The school is located at 250 Richard Montgomery Dr. in Rockville, just south of the center of Rockville.

Pets are not permitted at this shelter, except for registered service animals.

However, residents seeking shelter for their pets can drop them off in cages at the Bauer Drive Community Center at 14625 Bauer Dr. in Rockville. That facility also opens at 4 p.m., according to county spokeswoman Esther Bowring.
