2018 Hurricane Season

This is from our just finished State Report with Emergency Operations.  More information in detail will be forthcoming after the 2pm Weather Webinar.

 

State Report Update Synopsis 9-11-2018 12:30 pm:

Tropical L95 Update:

-The area of disturbed weather located over the extreme NW Caribbean Sea and the SE Gulf of Mexico is gradually becoming better organized.

...

-Ship reports indicate that this system is producing strong gusty winds over the Yucatan Channel and Upper-level winds are forecast to become more conducive for development.

-A Tropical Depression is forecasted to form by Thursday night while the disturbance moves across the western Gulf of Mexico. The Air Force Reconnaissance plan will be flying into the system on Wednesday morning.

-The chances for development are:
48 hours=50%
5 days = 70%

More information will be forthcoming after the 2pm briefing with the National Weather Service.

Cyclone Watches/Warnings could be issued as early as Thursday morning.  No matter what type of system forms, they are predicting heavy flooding rain, especially in the middle Texas Coast (our location) of a minimum of 7+ inches of rain per hour.  I will update after the next meeting.


Evacuation routes; it is as follows:

For your areas down there:  

35 to SH 172; take either SH 111 straight to 183 then continue on to Austin
or take I-10 into San AntonioI-10 or 
35 to 172 stay on 172 to Ganado, take Hwy 59 to SH 111 then 183 north,
continue on to Austin or San Antonio

Anywhere north of I-10 as far as possible will be good.

Jackson County Evacuation Routes

 

As everyone is aware, Hurricane season is coming up again. Those of you on the coast, make sure you have all necessary supplies in case of a storm threat.  If you know of any one with special needs, help them get in contact with the local emergency planner, or sheriff's office for information.

HURRICANE WATCH

HURRICANE WATCH

Tropical Depression Harvey Discussion Number 12
NWS National Hurricane Center Miami FL AL092017
1000 AM CDT Wed Aug 23 2017

Air Force Reserve Hurricane Hunter data indicate that Harvey has
regenerated in the Bay of Campeche, with a closed circulation
noted and a central pressure of about 1006 mb. The initial wind
speed is 30 kt based on SFMR data from the aircraft.

Harvey is not well organized at the moment, with an asymmetric cloud
pattern and a large radius of maximum wind. The environment,
however, is conducive for intensification while Harvey moves over
the very warm Gulf of Mexico waters in light-to-moderate shear. The
biggest hindrance to intensification in the short term is the poor
structure. Thus the NHC forecast will only show a gradual increase
in wind speed during the first day, with a more significant
intensification after that time. Although not explicitly forecast
below, we are anticipating Harvey being a hurricane at landfall
after the 48 hour forecast point. This forecast agrees well with
the guidance, almost all of which shows a quickly intensifying
cyclone approaching the Texas coast.

Since the center has just recently formed, the initial motion is
difficult to estimate, but the long-term motion is 310/8. Harvey is
expected to move more slowly toward the northwest or north-
northwest as it enters a weakness in the Atlantic subtropical ridge
during the next day or so. The ridge slightly strengthens by late
Thursday, which should cause a faster northwestward motion by then.
Around the time of landfall, however, Harvey should enter an area of
weaker steering currents near the upper Texas coast as high pressure
rebuilds over the southwestern United States. The storm should slow
down markedly over southeast Texas, and there is considerable
uncertainty on exactly how fast Harvey moves out of that state ahead
of the next mid-latitude trough. For now the NHC forecast will just
drift Harvey generally toward the east at days 4 and 5, on
the slow side of the model consensus. Hopefully later G-IV flights
and special soundings over the southern United States will help
clarify the long range forecast.

Key Messages:

1. Harvey is likely to bring multiple hazards to portions of the
Texas coast beginning on Friday.

2. Several days of heavy rainfall are likely across portions of
eastern Texas, Louisiana, and the lower Mississippi Valley from
Friday through early next week. This rainfall could cause life-
threatening flooding. Please refer to products from your local
National Weather Service office (www.weather.gov) and the NOAA
Weather Prediction Center (www.wpc.ncep.noaa.gov) for more
information on the flooding hazard.

3. The National Weather Service has issued a Storm Surge Watch
from Port Mansfield to High Island, Texas. There is the possibility
of life-threatening inundation from rising water moving inland from
the coastline during the next 48 hours in these areas. For a
depiction of areas at risk, please see the National Weather Service
Storm Surge Watch/Warning Graphic, available at
hurricanes.gov.

4. The Potential Storm Surge Flooding Map will also be available on
the NHC website by 1200 PM CDT. Remember that the Potential Storm
Surge Flooding Map does not represent a forecast of expected
inundation, but rather depicts a reasonable worst-case scenario -
the amount of inundation that has a 10 percent chance of being
exceeded at each individual location. Because the Flooding Map is
based on inputs that extend out only to about 72 hours, it best
represents the flooding potential in those locations within the
watch area.

5. Hurricane conditions are possible along the Texas coast from
Port Mansfield to San Luis Pass.

A Hurricane Watch means Hurricane wind conditions are possible somewhere within this area and within the next 48 hours A Storm Surge Watch means life-threatening inundation levels are possible somewhere within this area and within the next 48 hours * WIND - LATEST LOCAL FORECAST: Equivalent Tropical Storm force wind - Peak Wind Forecast: 30-40 mph with gusts to 55 mph - Window for Tropical Storm force winds: Friday morning until Saturday 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. * STORM SURGE - LATEST LOCAL FORECAST: Life-threatening storm surge possible - Peak Storm Surge Inundation: The potential for 4-6 feet above ground somewhere within surge prone areas - Window of concern: Begins Friday morning - CURRENT THREAT TO LIFE AND PROPERTY: Moderate - Emergency planning should include a reasonable threat for dangerous storm surge flooding of greater than 3 feet above ground. - To be safe, earnestly prepare for the potential of significant storm surge flooding impacts. Evacuation efforts should now be underway. - Life-threatening inundation is possible. Failure to heed evacuation orders may result in serious injury or loss of life. Leave if evacuation orders are given for your area. Consider voluntary evacuation if recommended. Poor decisions may needlessly risk lives. - POTENTIAL IMPACTS: Significant - Areas of inundation with storm surge flooding accentuated by waves. Damage to several buildings, mainly near the coast. - Sections of near-shore escape routes and secondary roads become weakened or washed out, especially in usually vulnerable low spots. - Major beach erosion with heavy surf breaching dunes. Strong and numerous rip currents. - Moderate damage to marinas, docks, boardwalks, and piers. Several small craft broken away from moorings, especially in unprotected anchorages. * FLOODING RAIN - LATEST LOCAL FORECAST: - Peak Rainfall Amounts: Additional 8-12 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.
