seen more bombings today. contessa. >> andrea mitchell reporting. it is hot and sticky. the thermometer beginning to rise. humid temperatures to climb into the 90s. for more on the conditions, rehema ellis is in central park. i thought the water might not be a bad place to be today. >> reporter: that's true, it might not be. it's also a good thing that many of them are starting very early this morning before the humidity and the heat index rises because another heat advisory is in effect today for the new york city area. but as you mentioned, it's not just of the new york city area that's experienced this. we're not alone. many parts of the country are feeling it too. across the country, the heat is on, and so is the search for ways to beat the punishing sun. >> it's been a little bit sweaty. we had to stop and change clothes. >> we make sure we drink a lot of water and stay in the shade
