WASHINGTON (AP) – The La Nina (lah-NEEN’-yah) climate phenomenon
has returned and that could be bad news for the drought-ravaged
south central states.
The periodic cooling of the tropical Pacific Ocean can affect
weather worldwide and often results in drier-than-usual conditions
across the southern tier of the United States and wetter than
normal conditions in the Pacific Northwest and Ohio Valley.
Mike Halpert, deputy director of the federal Climate Prediction
Center, says "this means drought is likely to continue in the
drought-stricken states of Texas, Oklahoma and New Mexico."
The forecasters said La Nina contributed to extreme weather
around the globe during the first half of this year and then faded.
They say it’s now re-emerged and is expected to gradually
strengthen and continue into winter.
