As Hurricane Irene storms toward the U.S. East Coast, two NCAR websites are tracking its potential path and strength.
NESL/MMM is running a high-resolution version of the Advanced Research Hurricane WRF (ARW) every six hours, at midnight, 6 a.m., noon, and 6 p.m. MDT. The output, with grid points separated by 4 kilometers (2.5 miles), appears on the real-time ARW page. Quick-look graphics include a hurricane's projected path and intensity and the cumulative precipitation expected along its path.
The results from a wide variety of tools used by forecasters at the National Hurricane Center and elsewhere are summarized at RAL's new Tropical Cyclone Guidance Project page (TCGP), which debuted earlier this month. Users will find a dedicated page for Irene, with track and intensity guidance updated every six hours. You'll also find a profile of the site on RAL's home page and an interview with its creator, Jonathan Vigh (ASP), at UCAR Magazine.
