Possible ‘Excessive Heat Warning’ This Weekend In CNY

The National Weather Service Out of Binghamton (NWS) has issued a Heat Advisory for all of CNY with the possibility for it to be upgraded to an 'Excessive Heat Warning' on Sunday.

Criteria for an Excessive Heat Warning is a heat index of 105° F or greater that will last for 2 hours or more. Heat Warnings are issued by the county when any location within that county is expected to reach criteria. For example: If you expected the heat index to reach 105°F in the city of Utica, an Excessive Heat Warning would be issued for that zone.

A heat warning means that some people can be seriously affected by heat if precautions are not taken. In addition to raising public awareness, the issuance of a heat warning will alert hospitals and officials to take certain actions to prepare and respond to an increase in emergency calls, and activate programs to check on elderly and the home-bound. In some cases, cooling centers can be open or designated and donation programs activated for fans and air conditioners. As in the case of an advisory, certain regulations may change such as turning off people's electricity, evictions, and outside work requirements.

MONDAY...

The NWS discussing the heat:

A long-duration heat wave will start on Saturday and intensify Sunday into Monday. The official NWS criteria for a heat wave is that the high has to reach 90 for three consecutive days. the heat index is not a high-temperature forecast taking into account both the heat and humidity...In terms of headlines, The NY state criteria for a heat advisory this year is now 95 degrees and where we expect afternoon heat index values on Saturday. Thus all of our NY counties are under an advisory for Saturday afternoon. Given very high confidence and high impacts for the heat going through Monday the advisory was expanded to cover the entire short-term period. An upgrade to an excessive heat warning with the potential for heat index values going over 105 may also be needed for Sunday and Monday afternoons.

* HEAT INDEX VALUES... From 95 to around 100 Saturday afternoon
than from 100 to locally 110 Sunday and Monday afternoons.

* TIMING... A prolonged heat wave will start on Saturday and
intensify Sunday and Monday with the highest heat index values
each afternoon. Hot and humid weather will continue through
most of next week.

* IMPACTS...The heat and humidity may cause heat stress during
outdoor exertion or extended exposure.

PRECAUTIONARY/PREPAREDNESS ACTIONS...
