Areas affected...Western and Northern Portions of the Florida
Peninsula

Concerning...Tornado Watch 660...

Valid 300510Z - 300615Z

The severe weather threat for Tornado Watch 660 continues.

SUMMARY...The tornado threat will continue along the west coast of
Florida into the overnight hours, expanding north-northeastward into
northern parts of the Florida Peninsula.

DISCUSSION...Hurricane Idalia continues to move north-northeastward
across the eastern Gulf of Mexico, and it is forecast by the
National Hurricane Center to make landfall tonight. Parts of the
outer rainbands of Idalia are currently located across the western
Florida Peninsula, where strong low-level shear is present. The
Tampa Bay WSR-88D VWP continues to show 0-3 storm-relative
helicities above 400 m2/s2. As Idalia moves further
north-northeastward, strong low-level shear is forecast to develop
across northern Florida early tonight. This will make conditions
favorable for tornadoes within the more discrete elements of the
outer rainbands.
