... Flash Flood Watch remains in effect from 2 PM EDT this
afternoon through late tonight...

The Flash Flood Watch continues for

* portions of northern Delaware, northeast Maryland, New Jersey,
and Pennsylvania, including the following areas, in northern
Delaware, New Castle. In northeast Maryland, Cecil. In New
Jersey, Camden, Gloucester, Hunterdon, Mercer, Middlesex,
Morris, northwestern Burlington, Salem, Somerset, Sussex,
Warren, and western Monmouth. In Pennsylvania, Berks,
Delaware, eastern Chester, eastern Montgomery, Lehigh, lower
Bucks, Northampton, Philadelphia, upper Bucks, western
Chester, and western Montgomery.

* From 2 PM EDT this afternoon through late tonight

* a hot and humid airmass will spread over the region today, and
then the remnants of what was tropical cyclone Barry will pass
through the region tonight. Showers and thunderstorms this
afternoon and tonight will be capable of producing torrential
rainfall, with local amounts of 2 to 4 inches and even higher
localized amounts potentially occurring in a short period of
time. This could lead to flash flooding.

* The risk of flash flooding is highest in urbanized and low-
lying areas. Rapid rises on small creeks and streams are
possible.

Precautionary/preparedness actions...

A Flash Flood Watch means that there is the potential for flash
flooding which can be life-threatening. Heavy rain is expected to
occur over a short period of time. Rapidly rising flood waters
may quickly inundate roadways and areas of poor drainage. Streams
and creeks could leave their banks, flooding nearby properties.

Please monitor the forecast, especially if you live in a location
that is prone to flooding. Be prepared to take action if a Flash
Flood Warning is issued for your area.

Issued: 3:14 PM EDT Jul. 17, 2019 – National Weather Service

... Heat advisory remains in effect until 8 PM EDT this evening...
... Excessive heat watch in effect from Friday afternoon through
Sunday evening...

The National Weather Service in Mount Holly has issued an
excessive heat watch, which is in effect from Friday afternoon
through Sunday evening.

* Heat index values... 100 to 110 today, then 110 to 115 Friday
through Sunday due to temperatures in the mid to upper 90s, and
dewpoints in the mid 70s. Some areas may reach 100 degrees for
daytime temperatures on Saturday.

* Timing... the highest heat index values will occur around mid
day. Additional advisories or warnings are expected during
subsequent days.

* Impacts... the excessive heat may quickly cause heat stress or
heat stroke.

Precautionary/preparedness actions...

A heat advisory means that a period of hot temperatures is
expected. The combination of hot temperatures and high humidity
will combine to create a situation in which heat illnesses are
possible. 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.

   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.

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