* * * HURRICANE ISAIAS UPDATE - 5:00 PM FRIDAY * * *
The wind field associated with Isaias is expected to expand
considerably as the system moves inland and becomes extra-tropical.
Strong winds will extend well east of the center of the storm and into
West-Central Georgia. A Tropical Storm Warning is now in effect for
this area where wind gusts to 60 mph will be possible. Further north
and east, while Isaias will be weakening and becoming post- tropical,
there will be a very strong pressure gradient between the system and
strong high pressure over the Mid-Atlantic. This gradient will support
a prolonged period of strong easterly winds with frequent gusts to
40 to 60 mph across most of North Georgia from tonight through early Sunday. A High Wind Warning has been issued for this area.
Areas to the south and east of these warnings have been placed in a Wind Advisory where winds will be weaker, but still have gusts to 45 mph. Across all areas, the prolonged and strong winds could lead to power outages from downed limbs and trees, especially when combined with saturated soils from periods of heavy rain.
Isaias will bring widespread rainfall, with multiple bands of heavy
rain expected tonight through early Sunday. Widespread rainfall totals of 1 to 4 inches are likely across much of the area, with a localized swath of up to 8 inches where the heaviest banding sets up. This rainfall could lead to flash flooding, particularly in urban and
poor-drainge areas, as well as flood-prone creeks and streams. The
north south orientation of bands make enhance river flooding along
north south reaches. Training heavy rain in the mountains may increase the risk of landslides. A Flood Watch has been issued for the entire area.
Additionally, as Isaias tracks northward and inland late tonight into
Saturday, a favorable environment for tornadoes will develop across
North and Central Georgia, and continue through Saturday night.
Several tornadoes will be possible, particularly within the outer
rainbands of the system. Tornadoes from tropical systems are typically quick to develop and short-lived, but with the forward speed of the system and the unique setup, we can't rule out a stronger (EF2 or EF3), long-track tornado, especially across Central Georgia.
