The heat is expected to intensify along the east coast this week, as tropical moisture levels and temperatures reaching 100 ° F (about 38 ° C) will hit large cities, from Boston to Washington.

On Sunday, the humidity was higher in areas of the northeast and southern Canada than in Florida, with some records shooting.

Until 6am. On Monday, the temperature exceeded 75 ° F (24 ° C) for about 190 million people in 33 states, which heralds minimal relief at night and early morning hours. In New York, the minimum temperature was 81 ° F (27 ° C), probably the earliest recorded minimum of 80 ° F in the history of measurements (since 1869).

Throughout the week, about 95 areas in Middle and Eastern states are projected to touch or break a record of maximum temperatures. About 150 areas in 31 states may record a record of hot nights, especially between Monday and Wednesday.

Towards the end of the week, heat to the east will be limited by clouds, rainfall and strong thunderstorms, although a new wave of high temperatures will move to the central states.

Record temperatures in many states

Maximum temperatures are expected to approach, equalize or even break the records in 23 states, from Illinois to Maine and further south to Georgia.

A record of hot nights may be recorded in 31 states, from Florida to Kansas and north to Michigan and Maine.

No east coast states will save the possibility of a record record.

In cities such as New York, Philadelphia, Baltimore and Washington, where a temperature of 100 ° F is expected to be approached or rejected by remarkable June records.

In many east coast states, the Heat Index is expected to range from 105 to 115 ° F (40–46 ° C) Monday to Wednesday, significantly increasing the risk of thermal stress and heat stroke. Alerts, warnings and recommendations for extreme heat have been issued for areas from Maine to South Carolina.

Until Thursday and Friday, heat is expected to retreat, as afternoon rains and thunderstorms will occur again on the east coast.

Abnormally high humidity

On Sunday, parts of the northeast of the US and South Canada presented higher levels of moisture even than those of Florida.

The maximum dew point prices – an indicator of the amount of water vapor near the ground – broke a June hour record: 26 ° C in Etaka, 25.5 ° C in Syracuse and 25 ° C in Toronto.

On Monday morning, more than 230 million inhabitants in 31 states were found under very high humidity conditions, while another 20 million in 15 states were facing extreme moisture levels.

Moisture is expected to culminate Monday night in parts of the northeast and the Mesatlantic, with the possibility of new records.

Throughout the week, waves of very high to extreme moisture will affect the southern, the Midwestern states and the central plains, with no substantial relief for the midnight or southeastern sector.

In many areas of the East and the Middle Ages there is a level of 4/4 risk for thermal stress for four or five consecutive days.

The phenomenon is attributed to tropical winds that carry warm and humid air from the Caribbean Sea and the Gulf of Mexico, where sea waves prevail, increasing both the temperature and the humidity of the atmosphere.

How much will it last

A cold front from Canada will bring a temporary relief from heat and humidity to the upper Middle Ages on Monday and Tuesday, and northeast on Friday – though it is unlikely to reach further south of New York.

In the Middle Atlantic and South Zone, there is no substantial change before the beginning of July.

Prior to this possible respite, a new heatwave and humidity wave is expected to move from the central plains and the intervals to the east the following weekend.

In addition to the US and South Canada, heatwaves are affecting southern Europe, the Middle East and regions of Asia. About 1.4 billion people worldwide are expected to experience extremely high temperatures, more than twice the people who are projected to experience unusual cold conditions.
