ANOTHER BUSY TROPICAL SEASON?
After a very active tropical
summer of 2004, preliminary indications show that another slightly above
average tropical cyclone season may be in store. Also, an above average
The list of names for the upcoming 2005 Atlantic Hurricane season includes: Arlene, Bret, Cindy, Dennis, Emily, Franklin, Gert, Harvey, Irene, Jose, Katrina, Lee, Marian, Nate, Ophelia, Philippe, Rita, Stan, Tammy, Vince, and Wilma.
Tropical cyclones that move inland across the region can produce problems ranging from catastrophic amounts of rain to tornadoes as well as straight-line wind damage. Typically August and September are most apt to see effects from tropical cyclones (Fig 1), although the early summer and fall months can see a few storms as well.

The different tracks along with intensity and location of landfall bring different weather impacts. These tracks range from systems passing west of the mountains, overhead the region, or to the east. Those tracking to the west typically have the least impact with those going directly overhead the most. Variations in impact can be significant depending on strength at landfall, speed of movement, and interactions with other weather features.
Systems that move overhead (Fig
2) tend to produce the most flooding and wind problems especially those that
pass inland off the
Those storms that slide east (Fig 3) of the region (through eastern VA or NC) provide for heavy rain but are highly dependent on strength and size of the system. They also can produce strong winds but generally few tornadoes.
Rainfall and wind effects are
usually much less with cyclones (or their remnants) moving west (Fig 4) of the
