1. A portable weather detection and alarm device comprising:
- an electromagnetic signal receiver that receives digital time signals and electromagnetic signals produced by lightning, wherein the digital time signals are transmitted to and received by the electromagnetic receiver at a stable fixed carrier frequency and the electromagnetic signals produced by the lightning are concentrated about the fixed carrier frequency and received at substantially the fixed carrier frequency;
a processor communicably connected to the electromagnetic signal receiver that processes the received time signals to determine accurate time data for display thereof on a display, and processes the electromagnetic signals produced by lightning to determine when an atmospheric event has occurred, and is operable to distinguish the received electromagnetic signals produced by the lightning from received digital time signals; and
an alarm connected to said processor that indicates the occurrence of an atmospheric event.

48. A portable weather detection and alarm device comprising:
-
a single electromagnetic signal receiver that receives digital time signals and electromagnetic signals produced by lightning;
wherein said receiver is operable to receive said electromagnetic signals and digital time signal at substantially 60 KHz;a barometric pressure sensor that detects atmospheric pressure; a processor communicably connected to said electromagnetic signal receiver and said barometric pressure sensor, wherein said processor processes said atmospheric pressure and said electromagnetic signals produced by lightning to determine when an atmospheric event has occurred, and wherein said processor creates an alarm threshold based on dynamic weighting of both atmospheric pressure and said electromagnetic signals, said processor operable to distinguish the electromagnetic signals produced by lightning from the received digital time signals for display on a display of information related to the received digital time signal; and an alarm connected to said processor that indicates the occurrence of an atmospheric event.
