Thousands were without power in Boston's Dorchester neighborhood Sunday during the hottest day of this week's prolonged heat wave. The temperature reached 100 degrees in Boston, tying a record from last summer and again breaking the previous daily record of 98 that was set back in 1933.

All across town people were feeling the heat, especially in Dorchester where as many as 7,500 Eversource customers had no power at one point. The company added that it was monitoring the outages amid the record heat, and crews were dispatched to make necessary repairs and restore the power as quickly and as safely as possible.

The utility company asked customers who did have power to be mindful, and not use large appliances during peak hours and raise the thermostat a few degrees to avoid overloading the grid.

People who spoke to NBC10 Boston said they were forced to leave their homes, while others showed up to businesses that were closed unexpectedly due to the outages.

Power was scheduled to be restored by 8:45 p.m. Sunday, Eversource said. More than 4,300 were still without power as of 10:20 p.m., according to the company's outage map.

Boston EMS said it has experienced a 15-20% increase in the daily call volume. Over 400 incidents have been reported each day since the heat wave began last Tuesday, and crews have responded to more than 80 incidents directly related to heat.

On Sunday, Boston Mayor Michelle Wu extended the city's heat emergency through Monday due to the hot weather that was forecast to last into Monday.

Much of the region has experienced temperatures 90 degrees or higher the past six days and some may have the opportunity to extend the heat wave to seven in a row Monday if the sun peeks through the clouds long enough ahead of an approaching frontal system. But the big story won’t be the heat and humidity,
