…TROPICAL STORM WATCH IN EFFECT…

A Tropical Storm Watch means Tropical storm wind conditions are
possible somewhere within this area and within the next 48 hours

* LOCATIONS AFFECTED
– Cuero

* WIND
– LATEST LOCAL FORECAST: Equivalent Tropical Storm force wind
– Peak Wind Forecast: 35-45 mph with gusts to 55 mph
– Window for Tropical Storm force winds: Friday afternoon
until Saturday afternoon

– CURRENT THREAT TO LIFE AND PROPERTY: Moderate
– Emergency planning should include a reasonable threat for
strong tropical storm force wind of 58 to 73 mph.
– To be safe, earnestly prepare for the potential of
significant wind impacts. Efforts should now be underway to
secure all properties.
– Dangerous wind is possible. Failure to adequately shelter
may result in injury.

– POTENTIAL IMPACTS: Significant
– Some damage to roofing and siding materials, along with
damage to porches, awnings, carports, and sheds. A few
buildings experiencing window, door, and garage door
failures. Mobile homes damaged, especially if unanchored.
Unsecured lightweight objects become dangerous projectiles.
– Several large trees snapped or uprooted, but with greater
numbers in places where trees are shallow rooted. Several
fences and roadway signs blown over.
– Some roads impassable from large debris, and more within
urban or heavily wooded places. A few bridges, causeways,
and access routes impassable.
– Scattered power and communications outages, but more
prevalent in areas with above ground lines.

* FLOODING RAIN
– LATEST LOCAL FORECAST:
– Peak Rainfall Amounts: 4-8 inches, with locally higher
amounts

– CURRENT THREAT TO LIFE AND PROPERTY: Elevated
– Emergency planning should include a reasonable threat for
minor flooding where peak rainfall totals are near amounts
conducive for localized flash flooding and rapid inundation.
– To be safe, prepare for the potential of limited flooding
rain impacts.
– Localized flooding is possible. If flood related watches
and warnings are issued, heed recommended actions.

– POTENTIAL IMPACTS: Limited
– Localized rainfall flooding may prompt a few evacuations.
– Rivers and tributaries may quickly rise with swifter
currents. Small streams, creeks, canals, arroyos, and
ditches may become swollen and overflow in spots.
– Flood waters can enter a few structures, especially in
usually vulnerable spots. A few places where rapid ponding
of water occurs at underpasses, low-lying spots, and poor
drainage areas. Several storm drains and retention ponds
become near-full and begin to overflow. Some brief road and
bridge closures.

* TORNADO
– LATEST LOCAL FORECAST:
– Situation is unfavorable for tornadoes

– CURRENT THREAT TO LIFE AND PROPERTY: None
– Emergency planning need not include a threat for tornadoes.
Showers and thunderstorms with strong gusty winds may still
occur.
– Little to no preparations needed to guard against tropical
tornadoes.
– Ensure readiness for the next tropical tornado event.

– POTENTIAL IMPACTS: Little to None
– Little to no potential impacts from tornadoes.
