Tonight millions of americans are bracing for Winter Weather from Mother Nature and only four weeks into fall. In fact, some parts of michigan have already reported more than 5 1 2 inches of snow. From the midwest to the northeast and far south to alabama, there are freeze warnings and watches. Out west, more rain is in the forecast, which could add insult to injury if more mudslides are triggered where waistdeep mud already shut down roads and trapped drivers this week. Nbc meteorologist dylan dreyer starts us off. Reporter a winter blast across the northeast and parts of the midwest today, from new york to michigan and pennsylvania. Snow has arrived, and its only october. I woke up this morning, and i said, happy birthday to my husband, i got you a gift.

Washington in new hampshire, temperatures there plunged to 20 degrees this morning, winds between 60 and 70 miles per hour. Hikers are being reminded to stay alert.

I mean, weve cleaned our house probably 15 times and cant seem to keep the mud out. Reporter now its the southwest bracing for rain, while new england bundles up. We are looking at the coldest air so far this season as this polar blast surges down from canada, and it is going to settle in across the midwest and the northeast, where we do have freeze warnings and freeze watches in effect that extend all the way down into tennessee. St. Louis is included in that, where tomorrow morning, temperatures will be close to freezing. Even lexington, kentucky, starting off the day at 29 degrees. Now, sunday afternoon not much of a rebound. Temperatures will be in the 40s and 50s. Cleveland about 48 degrees, new york city 51. Portland, maine, 48 degrees. Thats about ten degrees below average. Now, because of this colder air crossing over the relatively warmer waters of the great lakes, thats going to trigger lakeeffect snow in northwestern pennsylvania, up near erie. Could end up with one to three inches of snow. In the meantime, were looking at about one to three inches of rain out in the southwest. This is going to trigger flash flooding and also the potential of mudslides. Keep in mind, there is ample pacific moisture streaming in from the south. And we will see a widespread half an inch up to two inches. Some of the downpours could produce up to two to three inches of rain in a short period of time, so flash flooding and mudslides will be a big concern, especially as we go through tonight and throughout the day on sunday.

It was caused by a flow of warm, moist air from the same system that brought all that rain and flooding to Southern California this week. The dust and sand were whipped up by winds that gusted to more than 60 miles per hour.

Bill neely, nbc news, jerusalem. He is most wanted in both mexico and the united states, and tonight we are learning more about the recent Close Encounter authorities had with Joaquin El Chapo guzman, whose Sinaloa Cartel is the biggest elicit drug supplier to the u. S. Nbcs mark potter was the first to report that el chapo was injured and now has new details about the fugitive. Reporter with mexican troops still on their manhunt, the Mexican Security ministry issued a statement confirming the nbc news exclusive report that fugitive kingpin Joaquin El Chapo guzman is now injured, having suffered leg and facial wounds while moving quickly to avoid recapture. Three sources tell nbc news that american agents recently intercepted phone calls indicating chapo was hiding on a ranch in the rugged Sierra Madre Mountains near the tiny town of cosala. Mexican marines raided the ranch but faces heavy gunfire, and sources suspect chapo and his Security Team may have escaped on allterrain vehicles. Agents say chapo grew up in the mountains and knows where to hide and is protected by local residents, including officials he pays as lookouts. Get the word out, hey, theres Something Different going on here in the area, and that word spreads. Reporter chapo boosted his legendary reputation in july, when for the second time he escaped from a maximum security prison.

The sophisticated, milelong tunnel had lights and ventilation, and as we found, a motorcycle on tracks with a cart in front. Chapo guzman himself may have used the cart a little bit to come through the tunnel to escape. Reporter officials from that prison and a pilot are now charged with helping chapo escape. U. S.

The device is used as a nonsurgical alternative for women seeking permanent Birth Control. Our report tonight from nbcs anne thompson. Reporter it is the only nonsurgical, nonhormonal form of permanent Birth Control available. Unlike getting your tubes tied, the essure procedure is nonsurgical. Reporter approved by the fda, essure is used by 250,000 women. Some of those women, including kim hudak, are questioning the devices impact on their health. Physically, it has completely compromised my health in almost every aspect. Reporter she says over 14 years, essure has led to a host of problems severe headaches, spasms, bleeding, and eventually two surgeries, including a hysterectomy. Looking for answers online, kim discovered a Facebook Page about essure. At first, i was relieved, and then i was horrified that all these women had the same problems as i did. Reporter that group has more than 20,000 members with varying complaints. So, a device that women chose to avoid surgery may actually create a surgical need for them . Absolutely. Reporter now a new study led by dr. Art sedrakian of new yorks medicine, says planting the essure in the fallopian tubes can lead to more complications than traditional surgery, a risk that he says is ten times greater with essure. In many instances, we believe this is a reflection of the device failure, and these procedures are done to correct the failure of the device. Reporter bayer, the manufacturer, says over a decade of experience supports the safety of essure and that the single study has a number of limitations and makes several assumptions that require clarification. Dr. Sedrakian says he does not want the device banned. He wants women to have more information about potential problems. We asked the fda to take steps towards obtaining more highquality data. Reporter the fda is taking a second look at essure, listening last month to women and their doctors. The agency says it will review the study, calling the issue a high priority.
