As we pointed out earlier in the week, the projected path of Hurricane Irma shifted east bringing the effects into play for Cullman and surrounding counties: http://cullmantoday.com/2017/09/08/hurricane-irma-path-shifts-west-poised-affect-cullman/

Since that report, Irm’s path has shifted even further to the west. The expansive storm system is expected to pass directly over Cullman County and all of northern Alabama sometime over the next 48 hours. Irma will no longer be a hurricane when it passes over. IT will likely be either a Tropical Storm or Tropical Depression.

As a result, at 5:12 am this morning, the National Weather Service in Huntsville issued a TROPICAL STORM WATCH.

A Tropical Storm Watch means Tropical storm wind conditions are possible in Cullman County and surrounding areas within the next 48 hours. You can expect to see:

VERY HIGH WINDS: 30 to 40 mph sustained winds with gusts up to 60 mph

FLOODING RAINS: 2 to 4 inches with locally higher amounts

TROPICAL TORNADOES: None

The window for Tropical Storm force winds runs from Monday morning until Tuesday morning.

VERY HIGH WIND

The NWS rates the current threat to life & property from HIGH WIND as ELEVATED

The NWS strongly suggests the following:

1. Emergency plans should include a reasonable threat for tropical storm force wind of 39 to 57 mph.

2. To be safe, prepare for the potential of limited wind impacts. Remaining efforts to secure properties should now be brought to completion.

3. Hazardous wind is possible. Failure to adequately shelter may result in serious injury. Move to safe shelter before the wind becomes hazardous.

POTENTIAL IMPACTS: Limited

a. Damage to porches, awnings, carports, sheds, and unanchored mobile homes.

b. Unsecured lightweight objects are blown about.

c. Many large tree limbs broke off. A few trees snapped or uprooted, but with greater numbers in places where trees are shallow rooted. Some fences and roadway signs may be blown over.

d. A few roads impassable from debris, particularly within urban or heavily wooded places. Hazardous driving conditions on bridges and other elevated roadways.

e. Scattered power and communications outages.

FLOODING RAIN

The NWS rates the current threat to life & property from FLOODING RAIN as ELEVATED

The NWS strongly suggests the following:

1. Emergency plans should include a reasonable threat for minor flooding where peak rainfall totals are near amounts conducive for localized flash flooding and rapid inundation.

2. To be safe, prepare for the potential of limited flooding rain impacts.

3. Localized flooding is possible. If flood related watches and warnings are issued, heed recommended actions.

POTENTIAL IMPACTS: Limited
a. Localized rainfall flooding may prompt a few evacuations.

b. Rivers and tributaries may quickly rise with swifter currents. Small streams, creeks, canals, arroyos, and ditches may become swollen and overflow in spots.

c. 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.

d. Several storms drains, and retention ponds become near-full and begin to overflow.

e. Some brief road and bridge closures.

TROPICAL TORNADOES

TORNADO: The situation is unfavorable for tornadoes

The NWS rates the current threat to life & property from TORNADOES as NONE

1. Showers and thunderstorms with strong gusty winds may still occur.

2. Little to no preparations needed to guard against tropical tornadoes.

3. Ensure readiness for the next tropical tornado event.

POTENTIAL IMPACTS: Little to None
