Watches & Warnings

Excessive Heat Warning
Issued: 4:12 PM EDT Jul. 23, 2016 – National Weather Service

... Excessive heat warning remains in effect until 6 PM EDT
Monday...

* temperatures... highs in the mid to upper 90s through Monday.
Lows in the 70s, however in the highly urbanized areas such as
Center City Philadelphia the temperature at night may not drop
below 80 degrees especially Monday night.

* Heat index values... peaking between 100 and 105 degrees Monday
afternoon. The dew points are forecast to decrease some during
Sunday, resulting in heat indices peaking right near the air
temperature.

* Impacts... the excessive heat will create hazardous conditions.
The potential for heat related health issues will be high,
especially for the elderly and for those already in poor health.

* The multiple days of excessive heat will greatly affect those
who are attending outdoor activities, especially events with
large groups of people that are gathering in the direct sun.
Visitors not acclimated to the heat in our region this Summer
have a greater risk of being affected.

Precautionary/preparedness actions...

An excessive heat warning means that a prolonged period of
dangerously hot temperatures will occur. The combination of hot
temperatures and high humidity will combine to create a dangerous
situation in which heat illnesses are likely. Drink plenty of
fluids... stay in an air-conditioned room... stay out of the sun...
and check up on relatives and neighbors.

Take extra precautions... if you work or spend time outside. When
possible... reschedule strenuous activities to early morning or
evening. Know the signs and symptoms of heat exhaustion and heat
stroke. Wear light weight and loose fitting clothing when
possible and drink plenty of water.

Young children and pets should never be left unattended in
vehicles under any circumstances. During warm or hot weather car
interiors can reach lethal temperatures in a matter of minutes.

To reduce risk during outdoor work... the occupational safety and
health administration recommends scheduling frequent rest breaks
in shaded or air conditioned environments. Anyone overcome by
heat should be moved to a cool and shaded location. Heat stroke
is an emergency... call 9 1 1.
