Kent New Castle Sussex




Flash Flood Watch
Issued: 10:14 AM EDT Jul. 17, 2019 – National Weather Service

... 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.




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

... Excessive heat warning remains in effect until 10 PM EDT
Sunday...

* heat index values... 100 to 105 today, then up to 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 during the
daytime, especially on Saturday. However, given how hot and
oppressive this airmass will be, there will not be much relief
at night.

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

Precautionary/preparedness actions...

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 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.

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