Some cooling centers may be closed Wednesday as heat and other weather factors develop today

BREAKING: A published list of possible Allegany County cooling centers will be interrupted Wednesday during a multi-day, oppressive heat wave, with several other weather factors, including air quality and potential heavy rain entering the mix, starting today.

The Allegany County Health Department has published the list of county government and library locations which can be used as cooling centers during the National Weather Service (NWS)-declared HEAT ADVISORY which continues in effect from noon Tuesday through 8PM Thursday.

However, Wednesday is Juneteenth, a state and federally-recognized holiday, with county offices closed, including any senior meal sites normally operating on those days, and the David A. Howe Public Library in Wellsville which already is listing a closure on its calendar. Those seeking possible relief should call sites on the list in advance of Wednesday to determine availability.

In other weather-related activity:

— The NWS Weather Prediction Center is forecasting a Marginal Risk for excessive rain today as possible thunderstorms pass through the region. Less than a tenth of an inch of rain may fall in some areas, but the threat of downpours also exist in some of those locations.

— The HEAT ADVISORY is in effect from noon today through 8PM Thursday for Livingston County north.

— An AIR QUALITY ALERT exists in Cattaraugus and Wyoming counties west and in Rochester area counties from 11AM to 11PM today due to air quality levels in outdoor air being predicted to be greater than 105 for Ground Level Ozone.

The higher the level over 100, the greater the level of health concern for sensitive groups, including the very young and those with pre-existing respiratory problems such as asthma or heart disease.

— The maximum heat index forecast for Central Allegany County has backed off slightly for the next three days from the 100-degree level, but still is in the high 90s. The maximum is higher, however, to the east, being forecast at over-100 in Hornell.
