  Good evening, I'm John Yang. Across the South and West new all-time heat records could be set as forecasters say the week's long heatwave is entering its most intense phase. The forecast high in Las Vegas was 117 degrees. That's the hottest temperature ever recorded there. Nearly a third of all Americans are under heat advisories, watches and warnings. For some areas the heat wave has been unrelenting. Phoenix, Arizona has seen 16 straight days with highs over 110 and is on track to beat the record of 18 days. El Paso, Texas has set highs above 104 a month. There's also a record setting heat in the waters of Florida reaching the mid-90s. Not only does it make it harder for people to cool off, scientists warn of coral bleaching, fish kills and algae blooms and the warm waters could fuel tropical storms come hurricane season. Israeli Prime Minister Benjamin Netanyahu was taken to a hospital near Tel Aviv earlier today after feeling dizzy at his home. Doctors say it was likely dehydration.

The 73-year-old Prime Minister who's facing mounting Israeli anger over his bid to overhaul the judicial system is expected to remain in the hospital for more tests.
