…HURRICANE WATCH IN EFFECT…

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

• LOCATIONS AFFECTED
• Victoria

• Bloomington

• WIND

• LATEST LOCAL FORECAST: Equivalent Tropical Storm force wind
• Peak Wind Forecast: 35-45 mph with gusts to 60 mph

• Window for Tropical Storm force winds: early Friday morning
  until early Sunday morning

• 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: 6-10 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, 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.

Good afternoon,

Overview:

This update is to serve as situational awareness on the remnants of what was Tropical Storm Harvey, currently over the Yucatan Peninsula.

Satellite imagery this afternoon indicates an area of low pressure over the Yucatan Peninsula, associated with the remnants of Harvey, has become better defined. Environmental conditions are conducive for development when the system moves over the Bay of Campeche tonight. Conditions will remain favorable for a tropical depression to form in the southwestern Gulf of Mexico on Wednesday or Thursday. Confidence is increasing that the system will impact Texas Friday into the weekend.

There remains considerable uncertainty on exactly where the system could impact along the Texas coast and locations inland. As such it is too soon to determine exact impacts in South Central Texas as they will be highly dependent on the eventual track and intensity of the system.

Currently between 2-6” of rain is expected inland along and east of I-35, with isolated higher amounts, Friday through the weekend. Lesser amounts are expected west of I-35. It should be stressed that there is the potential for much higher amounts across South Central Texas if the center of system ends up tracking into the Mid or Lower Texas Coast and much lower amounts if the center of the system tracks toward the Upper Texas Coast. These rainfall forecast amounts are likely to change.

There is the potential for Tropical Storm Force winds inland Friday into Saturday east of I-35. However it is too soon to determine exact wind impacts.

A continued word of caution, there are snapshots of weather model output such as rainfall amounts and forecast tracks on social media for this weekend. It is extremely important that you not focus on any one particular model run this far out as these models will have drastic swings from run to run on tracks and rainfall amounts.

At this time we urge you to remain closely aware of the changes to the forecast over the next 24-48 hours by monitoring the National Hurricane Center (www.hurricanes.gov) and your local forecast (www.weather.gov/sanantonio). We expect greater detail and confidence in the forecast tomorrow.

Sincerely,

Jason Runyen & Jared Allen
