Facebook announces disaster communication tool

Facebook has announced implementation of a new communication tool designed to help people learn quickly whether a disaster has harmed their loved ones.

The tool, called “Safety Check,” will help users:

  • Let friends and family know they’re safe
  • Check on others in the affected area
  • Mark their friends as safe

Only the user’s friends will see the user’s safety status and the comments the user shares.

Safety Check will be available globally on Android, iOS, feature phones and desktop.

Facebook will activate the tool after any major disaster. When Facebook does so, any users who Facebook’s servers believe might be in the disaster area will receive a message through their Facebook accounts, asking if they’re safe.

Users may then indicate that they’re safe, or, if Facebook got their location wrong, that they’re outside the disaster area.

Whenever users mark themselves as safe, Facebook will send a message to all of the users’ Facebook friends to inform them.

Another way people can inform their loved ones that they are safe after a disaster is the American Red Cross’ “Safe & Well” program. Everyone who has access to the Web may go to the Safe & Well website and list themselves as safe and well. Users outside the disaster area may use the same website to search for registrants by name, phone number or home address.

Annual NWS winter outlook: Normal temps, below normal precip in Great Lakes

CPC winter outlook temperature mapCPC winter outlook precipitation mapIf you live in the Great Lakes states and don’t want another winter like last year’s you’re in luck. But if you’re a fan of winter sports, you might not be so happy with the annual winter outlook that the National Weather Service Climate Prediction Center issued today.

The outlook came out today And you can see on the maps above, the CPC predicts normal temperatures and below normal precipitation for the Great Lakes region.

Meteorologists are still watching for El Niño, an ocean-atmospheric phenomenon in the Tropical Pacific that affects global weather patterns. They say it has not yet shown up. If it does, it could affect the winter outlook.

NWS: Isolated/damaging gusts possible, watch unlikely


Isolated strong or even damaging wind gusts are possible in north-central and northeastern Indiana and southwestern Lower Michigan  overnight, according to a mesoscale discussion that the National Weather Service Storm Prediction Center (SPC) issued at 8:26 p.m. EDT. The SPC does not expect to issue a watch, however, because the overall threat is too low.

The loss of daytime heating has resulted in insufficient atmospheric instability to support widespread severe thunderstorms.

Meanwhile, a tornado watch remains in effect for parts of central, southern and extreme northwestern Indiana.

Latest outlook: More of Indiana at slight risk of severe weather

A larger part of Indiana has a slight risk of severe thunderstorms, according to an updated “Day 1 Convective Outlook” that the National Weather Service (NWS) Storm Prediction Center (SPC) issued at 3:45 p.m. EDT.

As compared to the SPC’s midday update, the latest outlook extends a slight risk area to include north-central and northwestern Indiana and part of northeastern Indiana. The outlook covers the period from 4 p.m. EDT today to 8 a.m. EDT tomorrow.

The slight risk area now includes all of IMO SKYWARN quadrant three and Huntington County of quadrant two.

The greatest threat is damaging straight-line thunderstorm winds of 58 mph or greater, but meteorologists cannot rule out a tornado.

People in the slight risk area should keep a reliable source of weather warnings accessible through the night and SKYWARN storm spotters should prepare for possible activation.

The SPC will next update its severe weather outlook for today and tonight by 9 p.m. EDT.

Little change in Indiana severe weather threat

Risk of severe weather between 12:30 p.m. EDT today and 8 a.m. EDT tomorrow. Red shaded area: Moderate risk. Yellow: Slight risk.

Source: SPC updated “Day 1 Convective Outlook” issued at 12:34 p.m. EDT.

Much of western and southern Indiana continue to have a slight risk of severe weather between 12:30 p.m. EDT today and 8 a.m. EDT tomorrow, according to an updated “Day 1 Convective Outlook” that the National Weather Service (NWS) Storm Prediction Center issued at 12:34 p.m. EDT.

The main changes since the previous convective outlook are:

  1. Removal of the “significant” damaging wind risk.
  2. Expansion of the moderate risk area eastward to cover more of Mississippi and part of Alabama.

In most of the counties served by the northern Indiana NWS office, strong storms remain possible, with a heavy rain threat. But as of the time of this writing, the risk of a severe storm in that area is very small.

The SPC plans to update its convective outlook again by 4 p.m. EDT.
