The National Weather Service (NWS) has issued a storm warning for parts of Oklahoma and Texas.

An ice storm warning is in effect for a portion of northwest Texas into southwest, central and northern Oklahoma. The storm is expected to continue into Tuesday night and have a significant impact on northwest and southwest Texas, as well as central and northern Oklahoma, The Weather Channel reported.

Along with winter storm warnings, the NWS has also issued winter weather advisories for areas in the central and southern Rockies, West Texas, and Oklahoma.

On Monday, the NWS Norman urged residents to brace themselves for the storm and warned of potential power outages.

“An Ice Storm Warning has been issued for portions of Oklahoma and western north Texas. With trees having most of their leaves still, prepare for widespread tree and power outages. Make sure to charge your devices and stay warm in case of power outages!” the tweet read.

Residents in Oklahoma have been encouraged to measure the ice that precipitates in their area to help the NWS track the accumulation from the storm.

“With ongoing winter precipitation and freezing rain accumulation, your reports are extremely important! Sending in photos are really useful, and mPing is useful for reporting precipitation type.” the NWS Norman account tweeted.

To provide the NWS with accurate measurements, residents should find a tree or shrub branch and use a tape measure or ruler to measure the ice on the top and bottom branch. However, the length of the branch should not be included in the measurement.

Since water typically drips, the ice on the bottom side of the branch will most likely be thicker compared to the top.

The two measurements should be divided by two to get the average of the ice that was accumulated. Locals can share their results via Twitter, Facebook, or email at sr-oun.spotter@noaa.gov.
