As Pakistan flood recovery efforts continue, the temperatures and heat indices are soaring.

On Sunday the heat indices were once again in the mid 50s Celsius (130 Fahrenheit) across much of southern and central Pakistan. Although most of the country has seen little rain over the past few days, the incredibly high temperatures and humidity have made for difficult living conditions for the millions of people that have been displaced from their homes.

Temperatures above 40 C (104 F) and heat indices into the lower 50s C (120s F) will continue at least into the early part of this week.

In Europe, a strong low pressure will move across the United Kingdom and towards Scandinavia on Monday. Severe weather warnings are in place for southern England, including London. Strong winds and up to 8 centimeters (3 inches) of rain will be possible, which could lead to flash flooding.

Afternoon heating will likely destabilize the atmosphere and lead to more severe storms from France to Poland. Strong winds, large hail, excessive rainfall, and isolated tornadoes will be possible.

Around the globe, the tropics are beginning to heat up.

On Sunday, Tropical Depression Six formed in the South China Sea and it is likely to become a tropical storm on Monday. Although it isn't expected to gain much strength before moving into northern Vietnam by the middle of the week, it will bring heavy rain and the threat of flooding.

In the East Pacific, Tropical Storm Frank was about 200 kilometers (125 miles) south of Puerto Angel, Mexico, on Sunday. Maximum sustained winds have increased to 95 kph (60 mph), and Frank is expected to become a hurricane by Monday afternoon.

Frank is moving parallel to the southern Mexico coast and is not expected to make a direct landfall. However, heavy rain and gusty winds from the outer bands have led to tropical storm watches and warnings being issued along the coast, including for Acapulco.

In the Atlantic, Danielle became the fourth tropical storm of the season on Sunday. Located about 1,165 kilometers (725 miles) west of the Cape Verde Islands, Danielle is not a threat to any land over the next five days.

Danielle will likely become a hurricane by the middle of the week as it moves to the west-northwest and eventually northwest.

Although it is early, computer models are currently forecasting Danielle to curve out into the north Atlantic without threatening the United States.
