Philadelphia is located at the confluence of the <?xml:namespace prefix = st1 ns = "urn:schemas-microsoft-com:office:smarttags" />Delaware and Schuylkill Rivers on the eastern border of Pennsylvania and is the largest city in Pennsylvania, belonging to the country of the United States of America (USA).  The region is considered Mid-Atlantic as it is located in north eastern USA.  <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

The history of Philadelphia goes back to when Philadelphia was founded by William Penn who was an English real estate entrepreneur philosopher.  Philadelphia also once served as a temporary capital city of USA in 1790-1800 when the federal city was under construction in the District of Columbia.  Tourism is now one of this cities main industries and Philadelphia is the 10th most visited city in the USA.  The Philadelphian accent shares some similarities with the New York and Boston accents.

The topography of Philadelphia is fairly flat with few points above 100ft.  The lowest point is sea level and the highest point is Chestnut Hill.  This flat topography gives little rise to the river bed which produces a tidal range of nearly 6ft in the harbour.  Storm surge, tidal action and run offs during storms can combine to produce threatening flood levels.  Flooding is a major problem related to tropical cyclones in Philadelphia.

The weather in Philadelphia is classed as a humid subtropical climate where summers are hot and muggy, spring and autumn are mild and winters very cold.  Snowfall varies as some winters may only bring mild snowfall and others could bring snow storms.  Precipitation is normally fairly evenly distributed throughout the year with maximum amounts sometimes flooding the Schuylkill River during the summer months. There are generally 8 to 11 wet days per month.  During the summer months high humidity is possible as a result of engulfed ocean air.  The average annual snowfall is 21 inches and the average annual rainfall is 42 inches.  The weather is said to be similar to Baltimore.  Spring and autumn are said to be the nicest seasons to visit Philadelphia when the weather is not too hot or too cold.

There are influences on the weather in Philadelphia such as the Alpachian Mountains which are to the west of Philadelphia and the Atlantic Ocean to the east which do moderate the climate reducing extremes of hot and cold weather.

Flooding is the most common natural disaster in Pennsylvania and this state has the highest flooding rate of any state in the USA.  Major earthquakes are not common in Philadelphia although tremors do occur.   In 1996 the winter snow storm which hit Philadelphia broke the record with 70.3 inches of snow falling causing major problems in the city.  The storm affected at least 50 million people.  There were 2 car pile ups reported and 9 people died as a result.

Philadelphiaâsâ culture is a must see of national historical sites such as Independence Hall where the declaration of independence was signed and museums of science, history, arts, and various other museums.  There is also a vibrant night life.  The avenue of arts contains restaurants, theatres for performing arts such as orchestras and the ballet, to name a few.  This city also plays a prominent role in music such as Philadelphia soul, rock music and jazz.  Football, hockey, baseball and basket ball are all played in major sporting leagues in Philadelphia too.
