This Hazardous Weather Outlook is for West Central And Southwest
Florida.

.DAY ONE...Today and Tonight.

...THUNDERSTORM IMPACT...
Numerous thunderstorms are expected to develop across west-central
and southwest Florida today. Although no organized severe weather
is anticipated, thunderstorms that develop will be capable of
producing strong gusty winds...locally heavy rains... and frequent
deadly lightning strikes. Heavy rainfall from persistent
thunderstorm clusters on top of already saturated soils in many
areas is likely to lead to localized flooding.

...RIVER FLOOD IMPACT...
Many local rivers and streams are running at elevated to flood
levels. Additional rainfall expected today will have the potential
to result in additional river rises from what is currently
forecast. Residents living along rivers and streams should remain
aware of water levels and be ready to move to higher ground
should flooding be observed.

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday.

...THUNDERSTORM IMPACT...
A wet pattern...characterized by scattered to numerous
thunderstorms will continue across west-central and southwest
Florida through much of the upcoming week. Although no organized
severe weather is anticipated, thunderstorms that develop will be
capable of producing strong gusty winds...locally heavy rains...
and frequent deadly lightning strikes. Heavy rainfall from
persistent thunderstorm clusters on top of already saturated soils
in many areas is likely to lead to localized flooding.

...RIVER FLOOD IMPACT...
River flooding will continue to be a concern on area rivers
through the remainder of the week. Areas of locally heavy rainfall
each day would contribute to further rises along area rivers if
the heavy rainfall falls within the river basin. Residents living
along rivers or faster flowing streams should remain aware of
water levels and be ready to move to higher ground should flooding
be observed.

.SPOTTER INFORMATION STATEMENT...

Spotter activation will not be needed today.
