Weather conditions play a significant role in crime scene investigations by impacting multiple aspects of the scene itself. When considering the influence of weather, it's important to recognize that it can alter the physical state of various types of evidence. For instance, rain can wash away footprints, dilute trace evidence, or even obscure blood stains. Extreme temperatures might affect blood spatter patterns or the rate at which biological evidence degrades. Additionally, visibility can be significantly hindered by fog, heavy rain, or snow, making it more difficult for investigators to observe and document the scene correctly. Accessibility is another crucial element; inclement weather can hinder access to certain areas of a crime scene, limiting what investigators can examine or collect, thus potentially impacting the overall investigation.

Understanding these influences helps investigators take appropriate precautions and develop strategies to mitigate the effects of weather during evidence collection and scene processing.
