National Weather Service reports the current temperature is 87 degrees and the heat index is 98 degrees. The heat emergency plan has been activated. Today, showers are likely and possibly a thunderstorm after 4pm with a high near 95. Tonight will be mostly cloudy with a low around 75. West wind 5 to 10 mph and chance of precipitation is 60%. As temperatures rise, the District of Columbia Fire and Emergency Medical Services Department and DC Water urge those in the District to beat the heat without tampering with fire hydrants. Unauthorized hydrant use can hamper firefighting, damage the water system and cause injury. It can also flood streets, creating traffic dangers and it can lower the water pressure for everyone on the block.Residents and visitors in the District can keep cool by staying in shade or air conditioning and drinking plenty of water. When the temperature or heat index reaches 95, residents are encouraged to take extra precautions against the heat. If they do not live in an air-conditioned building, they may take refuge at a District recreation facility, senior center or other air-conditioned building.
